Aiming at the problems of low efficiency,local conflict resolution and lack of practical application scenarios in the interaction model of multi-agent system in the distributed environment,this paper designs a multi-agent multi-slave interaction model based on Stackelberg game,which is applied to the interaction game between the controller and the participants in the command and control process.Firstly,through the optimization of Stackelberg game model and the multi-agent system of Stackelberg game of multiple leaders-follwers designed by multi-attribute decision-making,the closed-loop solution problem of Stackelberg game is solved by introducing a regular Riccati equation,which uses the optimization regularity of semi positive quadratic performance index.Then,based on graph theory,a multi-agent system model based on edge Laplace matrix is established to reduce the difficulty of solving complex problems.At last,numerical simulation and experimental analysis verify the efficiency and strong robustness of the model from many aspects.Moreover,it also proves that the proposed model is true and efficient.

Graphitic carbon nitride (g‐C3N4) has been widely explored as a photocatalyst for water splitting. The anodic water oxidation reaction (WOR) remains a major obstacle for such processes, with issues such as low surface area of g‐C3N4, poor light absorption, and low charge‐transfer efficiency. In this work, such longtime concerns have been partially addressed with band gap and surface engineering of nanostructured graphitic carbon nitride (g‐C3N4). Specifically, surface area and charge‐transfer efficiency are significantly enhanced through architecting g‐C3N4 on nanorod TiO2 to avoid aggregation of layered g‐C3N4. Moreover, a simple phosphide gas treatment of TiO2/g‐C3N4 configuration not only narrows the band gap of g‐C3N4 by 0.57 eV shifting it into visible range but also generates in situ a metal phosphide (M=Fe, Cu) water oxidation cocatalyst. This TiO2/g‐C3N4/FeP configuration significantly improves charge separation and transfer capability. As a result, our non‐noble‐metal photoelectrochemical system yields outstanding visible light (>420 nm) photocurrent: approximately 0.3 mA cm−2 at 1.23 V and 1.1 mA cm−2 at 2.0 V versus RHE, which is the highest for a g‐C3N4‐based photoanode. It is expected that the TiO2/g‐C3N4/FeP configuration synthesized by a simple phosphide gas treatment will provide new insight for producing robust g‐C3N4 for water oxidation. A single step for g‐C3N4, a giant leap for water splitting: A simple phosphide gas treatment of g‐C3N4 coated TiO2‐nanorod configuration not only narrows the band gap of g‐C3N4 by 0.57 eV into visible range but also generates a metal phosphide (M=Fe, Cu) water oxidation cocatalyst in situ. This TiO2/g‐C3N4/FeP configuration significantly improves charge separation and transfer capability, resulting in an enhanced photoelectrochemical water oxidation. [ABSTRACT FROM AUTHOR]

Constructing isotype g‐C3N4/g‐C3N4 heterojunction is an approach to improve the efficiency of g‐C3N4 towards solar‐assisted oxidation of water. Such functional configuration can effectively overcome the intrinsic drawback of rapid charge recombination of g‐C3N4. Here, a modified g‐C3N4, with homogeneous phosphorus doping, is prepared in this work through a phosphide‐involved gas phase reaction. The resulting P‐g‐C3N4 displays altered electronic structure, including upshifted band edge potential, narrowed band gap and improved electronic conductivity. These features allow P‐g‐C3N4 as an outstanding candidate to form isotype junction with pristine g‐C3N4. As expected, the accelerated charge separation and migration in target junction is validated by various measurements. The optimized isotype g‐C3N4/P‐g‐C3N4 heterojunction achieves a photocurrent as high as 0.3 mA cm−2 at 1.23 V vs RHE (AM 1.5G, 100 mW cm−2), representing 8‐fold's enhancement compared with pristine g‐C3N4. The present strategy for constructing g‐C3N4‐based isotype heterojunction networks is found effective for large‐scale manufacturing. Isotype photoanode: A phosphorus‐doped g‐C3N4 with suitable electronic structure was explored to construct metal‐free isotype photojunction in large‐scale manufacturing. The percolated networks exhibit largely increased photocurrent than its single component as a result of efficient charge transfer being qualitatively identified. [ABSTRACT FROM AUTHOR]

Allyl alcohol could provide an interesting model for chemocontrol in transition metal-catalyzed insertion of carbenoid into O H bond and olefin cyclopropanation. The chemoselectivity of PtCl 2 - and PtCl 4 -catalyzed (compared to Rh and Cu) reactions between methyl α-diazophenylacetate and unsaturated allyl alcohol has been carried out by DFT calculations. The potential energy profiles confirm that the intermediate free enol formed by intramolecular proton transfer is more favorable compared to the formation of the free ylide and cyclopropanation. The [1,3]-proton shift of the enol readily provides the final O H insertion product, which has a barrier of 4.5 and 6.9 kcal/mol using metal-assisted two-allyl-alcohol clusters as a proton shuttle. Calculations provide a good explanation for the O H insertion vs cyclopropanation of platinum, copper and rhodium catalysts have been used in these reactions. This study is expected to improve the understanding of platinum-catalyzed reactions for the C X bond construction and provide guidance for the future design of new catalysts and new reactions.
