| Abstract: | The platinum particles were electrodeposited on poly(2,5 dimethoxyaniline)(PDMAn) membrane modified electrode. The polymer was obtained by emulsion polymerization. The surface configuration and crystal orientation of Pt particles have been investigated by SEM and XRD. The results of the oxidation of isopropanol on platinized PDMAn modified electrode show that Pt particles deposited towards preferred orientation on Pt(200), and, the increase in polymer electroactivity due to proton doping affects the dimension and graininess of deposited Pt particles. The metallized polymer modified electrode is proved to be a "microheterogeneous catalysis system". At the metallized polymer electrode the oxidation of isopropanol mainly took place on Pt particles, and the polymer not only plays a role as a dispersion medium but also affects the catalysis property of Pt particles. |
