尿素辅助电解水是一种节能的制氢策略,但其应用受到阳极尿素氧化反应(UOR)和阴极析氢反应(HER)动力学缓慢的限制.以水热法合成的CoFe-LDHs/VMT(VMT为蛭石简写)催化剂作为UOR的高活性催化剂,通过XRD和XPS对催化剂进行表征.结果表明,VMT与CoFe-LDHs存在相互作用;CoFe-LDHs/VMT催化剂作为HER-UOR体系中的双功能电催化剂为实现节能制氢提供了新的途径.
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.
