| 摘 要： | 利用聚砜代替聚四氟乙烯,用循环伏安法,通过一步反应直接在高温裂解石墨(炭棒)电极上制备了Pt/C/聚砜型催化剂层.该催化剂层对甲醇的氧化呈现很好的电催化活性和稳定性,并系统研究了制备条件以及甲醇酸度、浓度对催化活性的影响.相对其他酸,在硫酸中电沉积所得Pt/C催化剂有更好的催化活性;催化剂的活性随甲醇溶液酸度的增加而增大;峰电流与甲醇浓度成正比.

| Abstract: | The layer of Pt/C/polysulfone(PSF) electrcatalyst is prepared by cyclic voltammetry methods on graphitic carbon.The effects of preparation conditions of the catalyst on its performance are investigated.The results of electrochemistry cyclic voltammetry tests show that graphitic carbon may be good candidates for catalyst support,Pt/C catalysts are deposited in H2SO4 solution having better catalytic activity for oxidation of methanol,the electrocatalytic activity increases with increasing the acidity of the C... |
