AI Technical Summary
Existing methods for preparing non-precious metal catalysts supported on two-dimensional tungsten carbide nanosheets are complex, costly, and have low yields, and their durability and catalytic performance in the water electrolysis process need to be improved.
Two-dimensional tungsten carbide nanosheets were prepared by reacting ethanol and hydrogen peroxide aqueous solution. The solid powder was obtained by mechanical stirring and heating evaporation, and then calcined in a tube furnace and reduced with non-precious metal salt and sodium borohydride to prepare a non-precious metal catalyst supported on two-dimensional tungsten carbide nanosheets.
The prepared catalyst exhibits excellent electrochemical oxygen evolution performance in water electrolysis, with low overpotential and large specific surface area, providing more active reaction sites. The method is simple, easy to prepare in large quantities, and low in cost.
