摘　　要：利用现场透射红外差谱方法研究了在无水1mol/LiClO_4甲醇溶液中甲醇在Pt电极上的阳极氧化.实验采用了细网格Pt电极和薄层电解池.各电位下的FTIR透射差谱反映了溶液中电极反应的变化.结果表明甲醇可被氧化成甲醛,且随电位的提高可进一步氧化成甲酸甲酯.The anodic oxidation of methanol on Pt electrode in 1 mol/L LiClO4 methanol solution was studied by use of voltammetry and in situ FTIR transmission differential spectroscopy method. A minigrid Pt optically transparent thin layer electrode was used as working electrode. The differential spectra were obtained between the sample potential and the background potential. The variations of transmission differential spectra at different potentials reflected the oxidation process carried out at t electrode surface. It was found that methanol could be oxidized into formaldehyde, and it could be further o lized into methyl formate at higher potential in water free solution.
