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

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. The moss-like Fe-Ni(OH)2@NiSe2 catalyst shows good catalytic ability for nucleophiles (e.g., ammonia, methanol and urea). Notably, the electrocatalytic activity for the urea oxidation reaction is the best, and it shows good electrochemical stability.

Automated summary

Iron-modified Ni(OH)2/NiSe2 catalyst exhibits superior selectivity, stability, and catalytic activity in urea oxidation reaction, as well as in oxidation reactions of other small molecules.
