Abstract
We propose a new, simple and effective strategy to enhance the electro-catalytic activity by regulating the valence states of the electro-catalyst. The proportion of Ni3+/Ni2+ on the ammonium nickel phosphate/nickel foam electrode surface was increased after H2O2 solution treatment. The kinetic analysis results showed catalytic rate constants (Kcat) of Ni3+-rich surface electrode (4.028
