铂基催化剂 meaning in English

platinum based catalyst

In order to improve the electro - catalytic activity of platinum based catalyst to methanol oxidation , in this thesis , firstly prepare heteropoly acid modified pt / gc electrode with different concentration by cyclic voltammetry method , and then test the cyclic voltammetry curves individually in vitriolic and methanol solution . the study shows the best concentration for both phosphomolybdic acid and phosphotungstic acid is 1 10 ~ ( - 3 ) mol / l . and find the more heteropoly acid modified on electrode , the lower peak - up potential towards methanol because of the existence of oxygenous species
为了改善铂基催化剂氧化甲醇的催化活性,本论文首先通过循环伏安扫描法制备了不同浓度磷钼酸和磷钨酸修饰的pt / gc电极,通过研究pt / gc电极在修饰前后在硫酸溶液中及含甲醇的硫酸溶液中的循环伏安行为发现,磷钼酸和磷钨酸均能在ptru / c电极上发生氧化还原反应,而且杂多酸修饰浓度对pt / gc电极氧化甲醇的催化活性有很大影响。
