Abstract

The pursuit of efficient and stable urea oxidation reaction (UOR) electrocatalysts is paramount for the sustainable utilization of renewable energy sources and the treatment of wastewater with urea content. This research introduces the successful fabrication of (Fe_0.5Ni_0.5)_0.96S/Co₉S₈/NF mesh heterojunction materials, which are replete with interfaces that facilitate enhanced catalytic activity. Benefiting from the electron transfer behavior from (Fe_0.5Ni_0.5)_0.96S to Co₉S₈, and the promotion of surface adsorption of SO₄²⁻, the (Fe_0.5Ni_0.5)_0.96S/Co₉S₈/NF electrocatalyst has excellent UOR catalytic performance. The experimental characterization and theoretical simulation show that the d-band center/thermodynamic barrier of (Fe_0.5Ni_0.5)_0.96S/Co₉S₈/NF is regulated by the redistribution of electrons at the heterojunction interface, and the adsorption of SO₄²⁻ on the surface. The reaction barrier of the adsorption strength/rate-controlling step of urea and reaction intermediates is optimized, which promotes the catalytic kinetics and thermodynamics of UOR, offering a promising strategy for advancing energy and environmental technologies.
