| 摘 要： | 双多孔氧化铝为样模，利用直流沉积法自组装纳米阵列Ｐｔ电极。该电极在Ｆｅ（ＣＮ）＾４－６溶液中的线性扫描伏安图呈现Ｓ型稳态曲线，对甲醇的氧化具有很高的电催化活性。另外，以该电极作为表现增强拉曼散射的活性基底，现场研究甲醇的电化学氧化过程，检测出中间产物单端吸附的ＣＯ。

| Abstract: | A novel method to fabricate an array of Pt nanoelectrodes by means of the porous alumina template was investigated. To evaluate the nanoelectrode arrays, linear sweep voltammetry in (CN)64- solution was performed and a sigmoidal shaped voltammogram was obtained. The electrocatalytic oxidation of methanol at the array of Pt nanoelectrodes was also studied. The results showed that the array exhibited high electrocatalytic activity in the oxidation of methanol.In situ Surface-enhanced Raman scattering spectra were measured for the reaction and the linearly absorbed CO species as the intermediates in the methanol electro-oxidation were detected. |
