| 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. |
