platinum based catalyst 解釋
鉑基催化劑
  • platinum : n. 【化學】鉑白金。 platinum metals 鉑族元素。 go platinum（唱片等）銷量達百萬張[上白金榜]。
  • based : 基準
  • catalyst : n. 【化學】觸媒，催化劑，接觸劑〈又作 catalytic agent〉；〈比喻〉觸發因素，〈口語〉（善用熱情、言語等打動他人的）有感染力的人。
  1. 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

    為了改善鉑基催化劑氧化甲醇的催化活性，本論文首先通過循環伏安掃描法制備了不同濃度磷鉬酸和磷鎢酸修飾的pt / gc電極，通過研究pt / gc電極在修飾前後在硫酸溶液中及含甲醇的硫酸溶液中的循環伏安行為發現，磷鉬酸和磷鎢酸均能在ptru / c電極上發生氧化還原反應，而且雜多酸修飾濃度對pt / gc電極氧化甲醇的催化活性有很大影響。
  2. The other key to the operation of a pem membrane is the thin layer of platinum - based catalyst that coats both of its sides and that represents 40 percent of the stack cost

    Pem隔膜的另一運作關鍵，則是鍍于隔膜兩面的薄層鉑觸媒，占電池組成本的四成。
