Electrolysis of industrial and human urea-containing wastewater is beneficial to the environment, using urea oxidation reaction (UOR) instead oxygen evolution (OER) saves energy effectively improves performance electrocatalytic hydrolysis for hydrogen production. The Co9S8/Ni3S2 nanosheet structures on nickel foam (NF) are an active hydrophilic catalyst UOR (HER). This electrocatalyst needs a low overpotential 136 mV attain 10 mA·cm–2 HER, it can reach current density 100 at working potential 1.36 V vs RHE. introduction Co element regulates both morphology electronic structure. former results in Co9S8/Ni3S2/NF offering more sites with larger specific surface area morphology, while latter drives S move direction binding energy. examination cobalt sulfides as bifunctional energy-efficient electrolytic H2 production purification urea-rich harmless has significantly advanced due this work.
