Research Progress on Cathodic Catalysts for Alkaline Water Electrolysis Hydrogen Production
Hydrogen energy is considered an ideal clean energy source for the 21st century due to the high energy density,green and pollution-free,and wide application.Hydrogen production by water electrolysis is one of the important methods to solve the energy crisis and environmental problems,among which the main problem of hydrogen production by alkaline water electrolysis is the high cost of catalyst.In order to reduce the cost of hydrogen production and improve the efficiency,researchers are committed to developing cheap cathode catalysts with excellent catalytic activity.the research progress of cathode catalysts by alka-line water electrolysis in recent years is summarized,and the efficient hydrogen evolution catalysts such as precious metal based catalysts,transition metal catalysts,alloy catalysts,and carbon based catalysts are dis-cussed.
