P-NiCoMo-LDH电催化5-羟甲基糠醛氧化制备2,5-呋喃二甲酸的性能
Preparation of 2,5-Furandicarboxylic Acid by Electrocatalytic Oxidation of 5-Hydroxymethylfurfural with P-NiCoMo-LDH
摘要
Abstract
Recently years,research on the catalytic oxidation of 5-hydroxymethylfurfural(5-HMF)to synthesize 2,5-furandicarboxylic acid(FDCA)has garnered significant attention.Compared with conventional thermal catalytic methods,electrocatalytic oxidation of 5-HMF offers advantages such as mild reaction conditions and reduced environmental pollution,making it a promising green and sustainable alternative.A P-doped NiCoMo-layered double hydroxide(P-NiCoMo-LDH)material with a unique sea urchin-like morphology was synthesized via a two-step process involving solvothermal treatment followed by high-temperature calcination.Its catalytic performance in the electrocatalytic oxidation of 5-HMF to FDCA was systematically investigated.The composition,structure,and surface chemical properties of the material were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),and X-ray photoelectron spectroscopy(XPS).Additionally,its electrochemical performance was evaluated through linear sweep voltammetry(LSV)and electrochemical impedance spectroscopy(EIS).The results demonstrate that the catalyst exhibits outstanding electro-chemical and catalytic performance.At an applied potential of 1.5 V(vs.RHE),the FDCA yield reaches 92.3%,with a Faradaic efficiency of 90.5%.Compared to undoped NiCoMo-LDH,these values represent increases of 44.3%and 40.5%,respectively.Furthermore,mechanistic studies and stability tests provide deeper insights into the catalytic mechanism of the P-NiCoMo-LDH material and its potential for FDCA synthesis.关键词
