Y3+和Tm3+对甲醇电氧化的影响

以光滑铂为电极, 采用循环伏安法研究稀土元素离子（Y³⁺和Tm³⁺）对甲醇电氧化的影响. 结果表明,Y³⁺和Tm³⁺呈现出较好的催化作用, 其加入使甲醇阳极氧化峰电流有较大提高, 分别增加120.10%和158.33%; 稀土元素对甲醇氧化的催化作用与其原子核外轨道电子排布及其在铂电极表面的吸附有关.

Effects of Y3 + and Tm3+ on Electro-oxidation of Methanol

The effects of the lanthanon ions （Y³⁺andTm³⁺） on the electro oxidation of methanol were studied with cyclic voltammetry, smooth platinum was used as research electrode. The results show that Y³⁺andTm³⁺ show the better catalysis, they could improve the anodic oxidation peak current of methanol to a great extent, which was increased separately by 120.10% and 158.33% at best. The catalyses of the lanthanon ions to the electro oxidation of methanol was analyzed that were relative to the electronic distribution of the Y and Tm atomsand their adsorption on the Pt electrode surface.
