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.

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.
