Iron-optimized oxygen vacancy concentration to strengthen the electrocatalytic ability of the urea oxidation reaction

Abstract

Iron-modified Ni(OH)₂/NiSe₂ enhances oxygen vacancies, expanding the electrochemically active surface area, which exhibiting superior selectivity and stability in urea oxidation reaction, outperforming pristine Ni(OH)₂@NiSe₂. It also demonstrates superior catalytic performance in the oxidation reactions of other small molecules.
