摘要：通过微波辅助法快速合成了非贵金属NiMoO_(4)纳米棒,作为电催化氧化甲醇的催化剂。采用X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线光电子能谱(XPS)对材料的结构、形貌进行了表征,并研究了其电催化氧化甲醇的特性。结果表明,NiMoO_(4)纳米棒在含有0.5 mol/L甲醇的1 mol/L KOH电解质中催化起始电位为0.45 V,在0.6 V时的催化电流密度达到了90 A/g,并具有良好的稳定性。因此微波辅助合成的非贵金属NiMoO_(4)纳米棒催化剂在直接甲醇燃料电池中具有良好的应用前景。
The non-noble metal NiMoO_(4) nanorods were rapidly synthesized by microwave-assisted method as the catalyst for the electrocatalytic oxidation of methanol.The structure and morphology of the material were characterized by XRD,SEM,TEM and XPS,and the characteristics of electrocatalytic oxidation of methanol were studied.The results show that the catalytic onset potential of NiMoO_(4) nanorods in 1 mol/L KOH electrolyte containing0.5 mol/L methanol is 0.45 V,and the catalytic current density at 0.6 V reaches 90 A/g,and has good stability.Therefore,the microwave-assisted synthesis of non-noble metal NiMoO_(4) nanorod catalyst has good application prospects in direct methanol fuel cells.
