碳掺杂Co3O4催化剂电催化氧化5-羟甲基糠醛的性能研究
Study on the performance of carbon-doped Co3O4 catalysts for the electrochemical oxidation of 5-hydroxymethylfurfural
摘要
Abstract
This study reports a series of carbon-modified Co3O4/NF(Co3O4/NF@Cx)catalysts.The morphology,phase composition,electronic structure,and electrochemical properties of the prepared materials were analyzed using various characterization techniques,including scanning electron microscopy,transmission electron microscopy,X-ray photoelectron spectroscopy,X-ray diffraction,and electrochemical testing(electrochemical active surface area and electrochemical impedance spectroscopy).The results indicate that 0.1 mol/L glucose is the optimal precursor concentration.The resulting Co3O4/NF@C0.1 exhibits a nanosheet structure,which enlarges the electrochemically active surface area,modulates the electronic structure,and accelerates charge transfer kinetics.Consequently,Co3O4/NF@C0.1 delivers excellent electrocatalytic performance for HMF oxidation:the potential required to reach 10 mA/cm2 is 273 mV lower than that for OER,with FDCA selectivity of>95%and faradaic efficiency of>94%.Meanwhile it also exhibits high HER activity.Furthermore,the catalyst retains 98%HMF conversion rate and excellent stability after five consecutive cycles.关键词
