以光滑Pt电极为工作电极,采用循环伏安法对酸性介质中甲醇及掺杂了少量Fe^2+的甲醇的电化学行为进行了研究。结果表明,Fe^2+/F^3+电对对甲醇的电氧化有较大的促进作用,氧化电流最多可提高65%,氧化电位可提前20~30mv。对Fe^2+/Fe^3+电对促进甲醇电氧化的可能机理进行了分析。
The electrochemistry behavior of methanol with a few Fe^2+ appending in acidic aqueous solution was investigated. The Cyclic voltammograms of the aqueous solutions were studied using platinum as working electrode. The result indicated that the appending of Fe^2 + / Fe^3 + had promotion effect to electro-oxidation of methanol. The additive could improve the anodic oxidation current of methanol by 65 percent and the peak potential moved ahead about 20~30 mV. The possible mechanism of promotion of the electron pair acceptor Fe^2 + / Fe^3 + to electro-oxidation of methanol was analyzed.
