Understanding the structure of the real catalytic active centre is a key factor to design a highly efficient catalyst and elucidate the mechanism of catalysis. Herein, graphene oxide supported ferrocenyl imine Pd/Co film was designed and prepared by self-assembly (GO@APTES-Fcl-Pdx/Co1−x) and characterized by water contact angle (WCA), scanning electronic microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy (RS), Brunauer–Emmett–Teller (BET), Fourier transform infrared spectroscopy (FT-IR), and electrochemical impedance spectroscopy (EIS) mesaurements. The GO@APTES-Fcl-Pd0.1Co0.9 film was used to catalyze the Suzuki cross-coupling reaction with a high activity (TOF, 11 353 h−1) and could be recycled at least 8 times. The heterogeneous catalytic mechanism was confirmed, and the real catalytic centres contained Pd, Pd/PdO, Pd/Co3O4(CoO/Co2O3), and Pd/PdO/Co3O4(CoO/Co2O3) clusters, in which Pd/Co3O4(CoO/Co2O3) as the main active species had the efficient synergistic effect between Pd and Co3O4 acted as the redox species, stabilizer, and support. Meanwhile, the ligand, organometallics, and carrier played an important role as the resource, stabilizer for the active centre, and in electron transfer from support to metals. The deactivation mechanism for the catalyst was mainly induced by the active center aggregation and the different facets of cobalt oxides formed during catalysis. [ABSTRACT FROM AUTHOR]

A key to understand relationships between structure and activity is help for rational designing high active catalytic films. In this research, a new bi‐cyclometallic ferrocene imine Pd(II)/Cu(II) catalytic monolayer supported on graphene oxide (GO@Fcl−Pd/Cu) was fabricated, which exhibited a higher activity (TOF=1.48×106 h−1) in Suzuki coupling reaction. Enhanced higher activity was related to the in situ formed Pd/ Cu2O (CuO) active centre on the surface during catalysis. Fe in ferrocene had the redox ability for making Pd0 more stability, meaning that Fe3+ was electron withdraw or donor during catalytic process, which could tune the electronic properties of the Pd and Cu in one complex and improve their electronic transferring to boost the activity. CuO/Cu2O could make Pd0 more negative and stability. Ensemble synergistic effect, including the metals, metal oxide, ligand and GO could be described as that the electron transferred from GO via ferrocene to Pd or via Cu(II) to Pd made more negative, improving the oxidative addition. Meanwhile, aryl boronic acid adsorbed on the vicinal Cu(II), Cu2O and CuO around Pd0 synergetic reaction easily with the Pd intermediate to form next intermediate. [ABSTRACT FROM AUTHOR]

Novel graphene oxide (GO)‐supported ordered diimine Ni/Pd bimetallic monolayers with ratio of Ni to Pd atomic ratios (2136 : 1, 333 : 1 and 97 : 1) (denoted as GO‐Diimine‐Ni/Pd1, GO‐Diimine‐Ni/Pd2, GO‐Diimine‐Ni/Pd3) were fabricated and their catalytic performances and synergetic mechanism were systematic investigated. For the as‐prepared GO‐Diimine‐Ni/Pd1, that trace palladium complex was responded for changing the electronic environment, tuning catalytic actives and modifying the electronic states which could enhance the highlighted catalytic activity. The more dramatic aspect of the GO‐Diimine‐Ni/Pd1 with high efficient catalytic activity could be achieved even with atom ratio of Ni/Pd even in 2136 : 1 (TOFNi=21277 h−1; TOFPd=4.545×107 h−1), in which the noble Pd could almost be replaced by non‐noble Ni according to requirement for economic chemistry. Interestingly, the synergetic mechanism between nickel and palladium was that the electron of Pd may transfer to Ni, which is different from the conventional Pd/Ni for catalyzing coupling reaction. Especially, the formation of Ni0 around Pd (II) as active centers was proposed and its size could be controlled with adjusting the palladium content on the surface. The results exhibited that the synergic effect between Ni and Pd made it easy for Ni2+ reduced into Ni0. It was crucial for adjusting the catalytic activity by designing the fine structure of ligand, the supports selection and modulating the Pd content at the molecular level. Prefect couple! Novel hetero‐bimetallic monolayers immobilized on GO containing different ratio of Ni/Pd were prepared, with which high catalytic activity can be achieved for catalyzing coupling reaction.The mechanism proved to be related to modifying structure, the supports and the synergic effect between Ni and Pd, in which trace Pd is crucial for making the Ni active center more negative.

A series of new cyclopalladated arylimine compounds ( 3a, 3b, 3c, 4a, 4b, 4c) were synthesized and characterized. Their catalytic properties for Heck and Suzuki in a homogeneous system were preliminarily investigated using water as solvent, in which no ligands, air isolation or assistant solvents were needed in . The optimization of the homogeneous system provided a basis for research on the heterogeneous catalytic reaction catalyzed by ordered self-assembly films. Organized monolayers of 3a, 3b, 3c were prepared and utilized as CC coupling catalysts. Monolayers of 3a, 3b, 3c were deposited using Langmuir-Blodgett techniques and analyzed using π-A isotherms, UV-visible and X-ray photoelectron spectroscopies and , which showed near orientation on the surface and stability under the optimized experimental conditions suitable for exploring Heck and Suzuki . The activity of immobilized 3c monolayer is enhanced relative to homogeneous reaction, in which the ordered monolayers are efficient with a catalyst loading as low as 10−5 mol%, turnover number as high as 79 200 and turnover frequency as high as 2640 h−1. The catalytic efficiency is 100 times higher than that in the homogeneous case using the same amount and ratio of reagent. The increased activity of immobilized 3c monolayer is due to a combination of its structure and changes in conformation when deposited onto the substrate. The topographic changes of catalyst films, stability of films and were investigated with , cyclic voltammetry, and atomic , from which a heterogeneous catalytic mechanism for Suzuki is proposed. The study demonstrates that careful monolayer studies can provide useful models for the design and study of supported molecular catalyst systems. Copyright © 2016 John Wiley & Sons, Ltd.

• A new heterogeneous GO@β-Ki-Pd 0.075 Ni 0.925 catalytic film was fabricated by the self-assembly method. • It had a higher activity with a higher turnover frequency (TOF) up to 112257 h−1 due to the ensemble synergistic of multi-active centers. • The active center includes Pd(0), Pd(0)/PdO, Pd(0)/Ni(0), Pd(0)/NiO, and Pd(0)/Ni 2 O 3. • The reasons for the deactivation are the aggregation of active centers, covered the active center, and loss of active metal. • Oxygen plays a crucial role in forming the metal oxides, acting not only as an essential function in synergy between metal oxide and palladium but also as a stabilizer. New self-assembly catalytic films (called GO@β-Ki-Pd 0.075 Ni 0.925 and Si@β-Ki-Pd 0.075 Ni 0.925) anchored on the surface of graphene oxide (GO), silicon wafer(Si) were prepared using bi-organometallic β-ketoimide (β-Ki) palladium/nickel by self-assembly and characterized by Fourier transform infrared spectroscopy (FT-IR), Raman spectra (RS), Ultraviolet-visible spectroscopy (UV-vis), X-ray diffraction (XRD), Water contact angle (WCA), Scanning electron microscopy (SEM), Atomic force microscopy (AFM), Transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET), Cyclic voltammetry(CV) and Inductively coupled plasma-atomic emission spectrometry (ICP-AES). Its catalytic performance, structure of the active center in suit formed, synergistic effect in the multiple active metals, and mechanism were systematically investigated using Suzuki-Miyaura cross-coupling reaction as a template. GO@β-Ki-Pd 0.075 Ni 0.925 exhibited a higher substrate adaptability and higher activity with 98 % yield (TOF value of up to 112257 h−1) and could be reused only four times. The catalytic mechanism was deeply explored using hot filtration, poisoning test, three-phase test, React IR, IR, Raman, SEM, TEM, XPS, BET, ICP-AES, and anaerobic experiments. The results confirmed that GO@β-Ki-Pd 0.075 Ni 0.925 acts as a heterogeneous catalyst, and catalysis occurred on the surface. The actual active centers in situ formed on the surface included Pd(0), Pd(0)/PdO, Pd(0)/Ni(0), Pd(0)/NiO, and Pd(0)/Ni 2 O 3 , exhibiting the whole synergistic, such as the electron density of Pd could be enhanced via the synergistic action between PdO, Ni(0), NiO, or Ni 2 O 3 and Pd(0) during catalysis, making more negative of Pd and easy for Pd react with an aryl bromide, boosting the catalyst's efficacy in oxidation addition reactions and elevating its catalytic activity overall. Oxygen plays a crucial role in formation of the metal oxides which not only have an important function in synergy between metal oxide and palladium but act as a stabilizer for active site (Pd(0)), and it can also maintain the balance ratio of PdO/Pd to prevent Pd from aggregation and affect the adsorption and desorption ability of the catalytic surface for some substrates. The deactivation mechanism was also systematically explored, and the results reveal that the accumulation of adsorbed materials on the surface, aggregation of the active centers, loss of Pd and Ni, and degradation of some organometallic in film were the main factors. Addressing these issues above is essential for optimal designing the higher active catalysts and practical application. Proposed the structure of the active center in suit formed on the surface during catalysis Multi-active sites having Pd(0), Pd(0)/PdO, Pd(0)/Ni(0), Pd(0)/NiO, and Pd(0)/Ni 2 O 3 in situ formed on the surface of bi-organometallic Pd(II)/Ni(II) self-assembly film supported on graphene oxide showed high catalytic activity due to the synergistic effect.

The designed ligand consisting of phenanthroline and Schiff-base groups could provide suitable sterics, electronics, and coordination demands, which are crucial for adjusting the catalytic activity by controlling distribution of active centres in 3D space with multi-direction, the synergies of Pd/Co and the properties of GO. • The designed ligand provide suitable steric, electronic, and coordination demands. • It is crucial to adjust the activity by controlling distribution of active centre. • GO@Fmp-Pd 0.25 Co 0.75 showed much higher activity compare with Pd or Co monometallic.

A new "Chanel like" diaminopyridine Pd(II) catalytic monolayer supported on Graphene Oxide (called GO@DAP-Pd) was prepared by self-assembly (SA) and characterized by XRD, Raman, FT-IR, SEM, TEM and XPS. Catalytic property of GO@DAP-Pd prepared use different Pd source in Suzuki coupling reaction was explored, in which the catalytic activity can be influenced with different palladium sources due to the different size of Pd nanoparticles formed. GO@DAP-Pd1 fabricated with (C 6 H 5 CN) 2 PdCl 2 as Pd source, exhibited a higher catalytic activity and could be reused at least 7 times. The deactivation of catalyst was mainly due to the aggregation of active Pd and the loss of a small amount of active Pd, resulting in the deactivation of the catalyst. The catalytic mechanism was detail explored by hot filtration, poisoning experiments, XRD, Raman, XPS and React IR, and the results showed that catalytic process occurred at the interface, including substrates adsorption, intermediate formation and product desorption. The structure and synergy in active sites containing PdO(110), Pd(200, 111) and Pd(111)/PdO(002) are crucial to enhance the catalytic activity. The method to form the multi-active sites in situ on the surface of organometallic monolayer can supply an efficient way to design and prepare the high active catalytic monolayer.

Electron transferring among the bimetals, support and ligand facilitated the formation of active center, resulting in higher catalytic activity. [Display omitted] • Sandwich Structured Aryl-diimine Pd/Co Catalytic Monolayer was fabricated. • The active center could be made more negative by the synergistic between Pd2+ and Co2+. • The results obtained by the kinetics analysis with React-IR showed that the GO@DiI-Pd 0.01 Co 0.99 prepared with certain ligand and supports in self-assembly way was much more active than homogenous catalyst. Self-assembled sandwich structured aryl-diimine Pd/Co catalytic monolayers linked with graphene oxide (GO@DiI-Pd x Co 1-x) were fabricated and characterized. The catalytic performance in Suzuki coupling reactions was systematically investigated, and GO@DiI-Pd 0.01 Co 0.99 exhibited higher catalytic activity with a Turn Over Number (TON) and Turn Over Frequency (TOF) (TON = 32,204, TOF = 6441 h−1) than monometallic catalysts when water was used as the solvent. The occurrence of heterogeneous catalysis was confirmed by hot filtration experiments, poisoning experiments, and dynamic studies using ReactIR. The synergistic effects between the different metals were investigated, and the catalytic activity could be enhanced by the palladium active center formed by the synergy between Pd2+ and Co2+, which also involved in the diimine ligands and graphene oxide. The special symmetric coordination sites of the aryl-diimine ligand accelerated electron transfer from GO to the metals or Co2+ to Pd2+, thereby making the palladium active center more negative and oxidative addition easier.

An efficient one-pot method involving visible-light-induced cyclization and Pd-catalyzed Suzuki cross-coupling processes to construct 3,4-diaryl coumarins is developed. Under the light on-off optimized conditions, a series of alkynoates and aryl boronic acids were well suitable for this catalytic system, and were successfully transformed into the corresponding products in moderate to high yields. Meanwhile, this synthetic system has good applicability for other Pd-catalyzed coupling reactions, such as Heck and Sonogashira reactions. 3,4,7-Triphenyl coumarin could be produced not only via the Suzuki reaction of 3-bromo-4,7-diphenyl with PhB(OH) 2 , but also via the Pd-catalyzed C–H activation. Based on the spectral studies, we found that some of the 3,4-diaryl coumarins may have AIE activities. This work provides a straight forward way to create valuable multi-substituted coumarins with potential AIE properties.

Two new Schiff-based cyclopalladated aryl imine catalysts (denoted as Fc-Pd and B-Pd) were prepared and their ordered self-assembled molecular monolayers (called as Si@F-Pd and Si@B-Pd) were fabricated. Their catalytic performances were evaluated using Suzuki coupling reaction as a templet with water as solvent, in which the structure on their catalytic properties and mechanism were systematic studied. Si@F-Pd and Si@B-Pd exhibited higher catalytic active with higher turnover number (TON) (149095 and 173214) and could be recycled at least 8 time and 6 time, respectively. The molecular structure and geometry of the catalyst was an important factor for their catalytic performance and stability, in which that large steric and structure made it easy to alter the electronic environment and structure, regulate the state of catalytic active surface which are contributed to their high catalytic activity. It was the fact that the electron rich of Pd may be formed by transferring electrons from ligand to Pd which became more nucleophilic for enhancing the facile oxidative addition with aryl halides. The catalytic mechanism proceeded a quasi-homogenous property on the surface in the form of leaching and re-deposition manner. Si@Fc-Pd acted as catalytic sites (surface) and sources or likely a reservoir for active species leaching, which formed a cycling state of equilibrium. It was clarified that the homogeneous and heterogeneous catalysis occurred at the same period on the surface and in solution, which was confirmed by hot-filtration, poison text, three-phase text, AFM, CV, XPS and ReactIR.
