Ga-modified CuFeO2 used as an efficient catalyst for CO2 hydrogenation to heavy olefins (C =5+) can achieve a high heavy olefin selectivity of 53.5%, which lies at a high level among reported catalysts, at a single pass CO2 conversion of 41.5%. It also displays an excellent long-term stability over 100 h, exhibiting its promising potential for industrial applications. [ABSTRACT FROM AUTHOR]

The design of heat-resistant energetic compounds generally employs symmetry, planarity, and multi-hydrogen bonds to obtain compounds with high density, good thermal stability, and low sensitivity. In this paper, a heat-resistant hydrazine-bridged compound, 6,6′-(hydrazine-1,2-diyl)bis(5-nitropyrimidine-2,4-diamine) (PHP), was designed and synthesized with the strategy of multi-fused conjugated structure constructed by hydrogen bonds. The compound featured high symmetry, high planarity, and strong conjugation with good thermal stability (364 °C). This strategy provides a basis for the design of heat-resistant energetic compounds.

Nitrogen-doped carbon nanotube confined CuCo nanoalloy catalysts are fabricated by using ZIF-67 as a sacrificial template for the one-pot selective hydrogenation of levulinic acid (LA) to 1,4-pentanediol (1,4-PDO). The optimal catalyst achieves a high 1,4-PDO yield of 87.8% at full LA conversion. It also exhibits good recycling stability and can be reused at least 5 times. [ABSTRACT FROM AUTHOR]

A bifunctional NiMoFe/Cu NW core–shell catalyst assembled into a practical solar-driven overall water splitting system leads to an unprecedented solar-to-hydrogen (STH) efficiency of 10.99% in neutral electrolytes, attributed to the synergic combination of a unique 3D self-supported core–shell architecture and rapid electron/mass transfer properties.

One-dimensional zig-zag chain and two-dimensional network dysprosium(III) single-molecule toroics with anisotropy barriers of about 5 and 31 cm−1 under a zero dc field are reported. These are the first one- and two- dimensional homometallic single-molecule toroics reported to date. Furthermore, the two complexes also display white-light emission under UV-light irradiation.

Excellent photoelectrochemical activity was demonstrated for an easily prepared porous Ni-O/Ni/Si photoanode with an onset potential of 0.93 VRHE, a photocurrent of 39.7 mA cm−2 at 1.23 VRHE, an energy conversion efficiency of 3.2% and a stability above 100 h. [ABSTRACT FROM AUTHOR]

Lowering the dimension of transition metal dichalcogenides is an efficient approach to expose more S-edge-sites. Here, zero-dimensional MoS2 and WS2 nanodots are successfully prepared with the assistance of a template of NiNi Prussian blue analogue nanoplates. The novel hybrids exhibit highly efficient and stable catalytic ability for the hydrogen evolution reaction. [ABSTRACT FROM AUTHOR]

Reversible crystal-to-crystal transformation between a linear trinuclear Fe(ii) complex [Fe3(NH2-trz)6(SCN)5(H2O)] (SCN)·4H2O (1, NH2-trz = 4-amino-1,2,4-triazole) and a 1D chain [Fe3(NH2-trz)6(SCN)5]n(SCN)n (1a) and the SCO behaviour change have been studied by X-ray single-crystal diffraction, magnetic measurements and DSC. Complex 1a exhibits one more SCO step at a low temperature. [ABSTRACT FROM AUTHOR]

A porous carbon layer was inserted between a BiFeO3 film and a Pt catalyst for efficient solar water splitting. A photocathodic current density of −235.4 μA cm−2 at 0 V versus RHE and an onset potential of 1.19 V versus RHE were obtained under 100 mW cm−2 Xe-lamp illumination. [ABSTRACT FROM AUTHOR]

Pb(Zr0.2Ti0.8)O3 wrapped CaFe2O4 particles were constructed on ITO coated quartz as a photocathode for efficient water splitting. A photocurrent of 152 μA cm−2 was obtained under zero bias vs. Ag/AgCl and 100 mW cm−2 with the assistance of positive poling and Ag decoration. [ABSTRACT FROM AUTHOR]

Three 5,5′-azotetrazolate based Zn(ii) and Ni(ii) complexes exhibit novel supramolecular structures and emit multi-photoluminescence under laser excitation and the multi-photoluminescence promises a multi-channel signal photoluminescent material. [ABSTRACT FROM AUTHOR]

Novel multifunctional magnetic-mesoporous Janus particles with controlled aspect ratio were developed by a simple one-step synthesis approach. Due to their superior magnetic properties and well-defined pore structures, these particles will be important in drug delivery, molecule targeting, cellular imaging, and as building blocks for the assembly of complex nanostructures.
