中文摘要: 以H2PtCl6为初始原料,采用水解法制备了H2Pt(OH)6,然后用化学沉淀法制备了20%Pt/C催化剂。对其结构和形貌特征采用TEM、XRD、XPS进行分析和表征,并采用循环伏安法和计时电流法评价了催化剂的电化学性能。结果表明,所制备的催化剂铂颗粒分散均匀,大小约2.1 nm,表面无Cl-,具有良好的电化学性能。
Abstract:Chemical deposition method was used to prepared 20%Pt/C catalyst with precursor of H2Pt(OH)6 prepared from H2PtCl6 by hydrolysis method. The structure, morphology and electrochemistry performance of 20%Pt/C catalyst were characterized by XRD, TEM, XPS, cyclic voltammetry and chronoamperometry. The results show that uniformly dispersed with size of about 2.1 nm and no Cl- on the surface of catalyst, the Pt particles has good electrochemical properties for methanol oxidation.
