  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. Catalytic synthesis of cyclohexanone ethylene ketal with h3pw6mo6o40 tio

    二氧化鈦負載磷鎢鉬雜多酸催化合成環己酮乙二醇縮酮
  3. Because the tungsten from the phosphotungstic acid could pull out and deposit on the surface of catalyst, and the electronegativity of mo - o is smaller than that of w - o. the smaller the electronegativity is, the higher oxidation activity is. thus phosphomolybdic acid shows better catalytic oxidation activity than phosphotungstic acid

    由於磷鎢酸中的鎢可以脫出並少量沉積到催化劑表面，而且從電負性來說mo - o的鍵能小於w - o ，鍵能小的雜多酸有較強的氧化性，所以鉬系雜多酸催化活性要好於鎢系雜多酸。
  4. The morphology of the catalysts was characterized with a transmission electron microscope ( tem ). modified the three electrodes with two different heteropolyacid respectively and test the well modified electrodes using the cyclic voltammetry and amperometric i - t curve

    分別採用磷鉬酸和磷鎢酸對三種催化劑得到的催化電極進行了修飾，並用循環伏安曲線和不同電位下的恆電位i - t曲線測試了它們的性能。
