FeNiCoMoPCB高熵非晶合金电催化析氧性能
Oxygen evolution reaction performance of FeNiCoMoPCB high-entropy amorphous alloy
摘要
Abstract
To address the insufficient stability of amorphous alloys during long-term oxygen evolution reaction(OER)processes,this study integrated the compositional design concept of high-entropy alloys into the material development of conventional amorphous alloys to enhance their catalytic durability.By leveraging the high-entropy effect of amorphous alloys,the electrocatalytic OER performance of Fe50Ni10Co10Mo10P10C5B5 high-entropy amorphous alloy wires was systematically evaluated.The surface structure was regulated through an electrochemical dealloying approach,which significantly improved the catalytic activity of the material.The results indicate that after electrochemical dealloying in 0.5 mol/L sulfuric acid(H2SO4)for 1 h,the high-entropy amorphous alloy wire exhibits an OER overpotential of only 241 mV and a Tafel slope of 48.1 mV/dec in 1 mol/L potassium hydroxide(KOH)solution at a current density of 10 mA/cm2.Moreover,after prolonged electrochemical operation(>242 h),the OER performance shows no significant degradation.The high-entropy amorphous alloy exhibits excellent catalytic activity and long-term stability in alkaline media,which is primarily attributed to the synergistic stabilization effect arising from the highly active surface of the amorphous structure and the configurational entropy associated with the multi-principal-element composition.This research can provide reference for the development of highly active and stable high-entropy amorphous alloy catalysts.关键词
