Background
The hydrogen energy has the advantages of high combustion heat value, cleanness, no pollution and the like, and is widely paid attention to researchers. At present, the main source of hydrogen is still fossil fuel hydrogen production, and the method has a strong scale effect although the process is mature, but the fossil fuel hydrogen production can emit a large amount of carbon dioxide to destroy the environment, which is contrary to the current concept of protecting the environment, saving energy and reducing emission. Therefore, it is urgent to find a new hydrogen production path. In recent years, the hydrogen production by water electrolysis has the advantages of cleanness, environmental protection, higher purity of the prepared hydrogen and the like, and is widely paid attention to researchers. However, the disadvantages of high overpotential and high cost of hydrogen production by water electrolysis limit the industrial application prospect. In order to solve the problems, the overpotential of the catalyst is reduced by using the catalyst with excellent performance, and the improvement and the cost reduction are important realization schemes for effectively utilizing future resources.
In the previous researches, noble metals are generally considered as excellent-performance electrolyzed water oxidative coupling hydrogen production catalysts, but the development of the catalysts is restricted due to the defects of high price, less raw materials and the like. Research in recent years has focused on reducing precious metal loadings or using inexpensive and enormous reserves transition metals to develop novel electrolyzed water oxidation coupled hydrogen production catalysts. The traditional catalyst synthesis method and device, such as hydrothermal synthesis method and device, have the defects of high requirement on synthesis conditions, incapability of large-area preparation and the like, and limit the further development of catalyst research.
