Time-Decoupled Electrolysis via a Rechargeable Metal-Urea Battery for Waste Urea Treatment and Hydrogen Production.

ABSTRACT: The resource utilization of urea wastewater is an important issue in the environmental field. In the present work, urea can be used as the resource of pure hydrogen production by a temporally decoupled rechargeable metal-urea battery. During the cathodic charging process, urea is dissociated by the reaction of CO(NH₂)₂ + 6OH^-→ N₂ + 5H₂O + CO₂ + 6e^- to achieve the disposal of urea. Water is splitting into hydrogen (2H₂O + 2e^-→ H₂ + 2OH^-) during the cathodic discharging process, accompanied with the production of electrochemical energy. The key catalyst layers at the cathode employed bifunctional Ni/Mo₂C electrocatalysts for both the urea oxidation reaction (UOR
