Electron modulation of cobalt carbonate hydroxide by Mo doping for urea-assisted hydrogen production
文献摘要：
Combining urea oxidation reaction(UOR)with hydrogen evolution reaction(HER)is an effective method for energy saving and highly efficient electrocatalytic hydrogen production.Herein,molybdenum-incorporated cobalt carbonate hydroxide nanoarrays(CoxMoyCH)are designed and synthesized as a bifunctional catalyst towards UOR and HER.Benefiting from the Mo doping,the dispersed nanoarray structure and redistributed electron density,the CoxMoyCH catalyst display outstanding catalytic perfor-mance and durability for both HER and UOR,affording the overpotential of 82 mV for HER and delivering a low potential of the 1.33 V for UOR(vs.reversible hydrogen electrode,RHE)to attain a current density of 10 mA cm-2,respectively.Remarkably,when CoxMoyCH was applied as bifunctional catalyst in a two-electrode electrolyzer,a working voltage of 1.40 V is needed in urea-assisted water electrolysis at 10 mA cm-2 and without apparent decline for 40 h,outperforming the working voltage of 1.51 V in con-ventional water electrolysis.
