Fe-Doped Ni₂P/NiSe₂ Composite Catalysts for Urea Oxidation Reaction (UOR) for Energy-Saving Hydrogen Production by UOR-Assisted Water Splitting

Inorganic Chemistry, Год журнала: 2024, Номер 63(19), С. 8925 - 8937

Опубликована: Апрель 29, 2024

The development of efficient urea oxidation reaction (UOR) catalysts helps UOR replace the oxygen evolution (OER) in hydrogen production from water electrolysis. Here, we prepared Fe-doped Ni2P/NiSe2 composite catalyst (Fe–Ni2P/NiSe2-12) by using phosphating-selenizating and acid etching to increase intrinsic activity active areas. Spectral characterization theoretical calculations demonstrated that electrons flowed through Ni–P–Fe–interface–Ni–Se–Fe, thus conferring high Fe–Ni2P/NiSe2-12, which only needed 1.39 V vs RHE produce current density 100 mA cm–2. Remarkably, this potential was 164 mV lower than required for OER under same conditions. Furthermore, EIS driven Fe–Ni2P/NiSe2-12 exhibited faster interfacial reactions, charge transfer, response compared OER. Consequently, can effectively prevent competition with NSOR, making it suitable UOR-assisted Notably, when electrolysis is operated at a 40 cm–2, system achieve decrease 140 traditional This study presents novel strategy splitting energy-saving production.
