Urea-assisted electrolysis water represents an energy-efficient strategy for hydrogen production.However,its potential application is hampered by the sluggish kinetics of the urea oxidation reaction(UOR)at the anode and the hydrogen evolution reaction(HER)at the cathode.In this study,CoFe-LDHs/VMT,a highly active catalyst,is synthesized via a hydrothermal method,and employed for enhancing the UOR.The characterization of the catalyst by XRD and XPS reveals the interaction between VMT and CoFe-LDHs.Experimental results demonstrate that the CoFe-LDHs/VMT catalyst exhibits excellent electrocatalytic performance in the bifunctional system of HER and UOR,providing a new pathway for energy-efficient hydrogen production.
