Ce-CoFe-P@CC纳米复合催化体系的OER性能
OER Performance of Ce-CoFe-P@CC Nanocomposite Catalytic System
摘要
Abstract
Powder electrocatalysts usually need adhesives for electrocatalytic performance testing,resulting in an increase in resistance,a decrease in catalyst load,and easy stripping of the catalyst under long-time testing.Ce-doped CoFe layered bimetallic hydroxides were uniformly grown on carbon cloth by one-step hydrothermal method,and the adhesive-free Ce-CoFe-P@CC self-supporting electrocatalyst was obtained by further phosphating treatment.It was characterized by XRD,SEM,TEM,N2 adsorption-desorption isotherm and XPS,and its electrocatalytic OER performance was tested.The results show that the synthesized electrode material has regular thin nanosheet morphology,and the length and thickness of the nanoflake are 2.50 μm and 0.05 μm,respectively.The doping of Ce and P optimizes the electronic structure of CoFe-LDH,promotes the charge transfer,increases the catalytically active site,and improves the durability of the electrode.The Ce-CoFe-P@CC only needs an overpotential of 187 mV at a current density of 10 mA/cm2,showing excellent OER catalytic performance.关键词
