分别以相同面积的光滑 Pt电极和吸附了 Sm3+ 的铂电极作为工作电极 ,在酸性介质中采用循环伏安法对甲醇氧化进行测定 .结果表明 ,吸附了 Sm3+ 的 Pt电极上产生了更大的氧化电流 ,表明 Sm3+ 的加入对甲醇的电催化氧化起到了促进作用 .这一研究结果在直接甲醇燃料电池 ( DMFC)阳极催化剂研制方面具有较大的应用潜力
The oxidation of methanol was determined by cyclic voltammetry using acidic Pt as the working electrode with smooth Pt electrode of the same area and platinum electrode adsorbed by Sm3 + as the working electrode respectively. The results showed that more oxidation was produced on the Pt electrode adsorbed by Sm3 + Current, indicating that the addition of Sm3 + promoted the electrocatalytic oxidation of methanol.The results of this study have great potential in the development of direct methanol fuel cell (DMFC) anode catalyst
