Background
With the increasing prominence of the problem of energy shortage, the development and utilization technology of novel renewable energy sources is more and more paid attention by people. As a novel clean energy, the hydrogen has important significance for solving the problem of environmental pollution by overcoming the problem of energy shortage and realizing zero emission. The water electrolysis is a technology for conveniently and efficiently obtaining hydrogen, but the overpotential commonly existing in the reaction process causes excessive consumption of energy. The novel water electrolysis catalyst is designed, so that the overpotential in the water decomposition process is effectively reduced, and the novel water electrolysis catalyst has important practical value for reducing energy consumption and improving the water electrolysis efficiency.
The metal organic framework has the advantages of high specific surface area, open structural framework, more metal active sites, easy regulation and control of components and the like, and has important application value in the fields of gas adsorption, sensing, catalysis and the like. However, the application of the metal organic framework in the field of electrocatalysis is has been limited due to the disadvantages of poor conductivity, low electron transfer efficiency, etc. Recent studies have shown that metal organic framework materials with sheet structures can expose more catalytically active sites and thus have higher catalytic activity. However, the sheet metal organic framework is easy to stack in the preparation process, and the sheet structure still cannot solve the defect of poor conductivity. In addition, the preparation of the sheet metal organic framework material at present adopts a layer-by-layer assembly method, and the preparation process is complex, long in time consumption and difficult to control; the polymer cross-linking agent used in the process can also cover the active sites of the polymer cross-linking agent, and reduce the catalytic activity and stability of the material. Therefore, the development of the efficient and practical preparation method of the sheet metal organic framework material has important significance. Meanwhile, the inherent defect that poor conductivity is a metal organic framework material is considered, the catalyst is combined with a material with relatively better conductivity while the catalytic activity of the catalyst is not influenced, the synergistic effect between the catalyst and the material is fully exerted, and the catalyst has important significance for preparing a novel efficient electrolyzed water catalyst.
