The results showed that PmClAn had an excellent electroactivity and proton doping increased the electroactivity. The Pt particles electrodeposited on PmClAn trend towards preferred orientation, and Pt(200) was the preferred face. It was also found that platinized PmClAn promotes isopropanol oxidation, the polymer is not only as a dispersion media of Pt particles forming a "microheterogeneous catalysis system", but also has effect on electronic properties of Pt.展开更多

Cyclic voltammetric experiments showed that, in NaClO4 solution, the film electrode has one pair of well defined and relatively stable reduction and oxidation peak. For this pair of peak, Epc=-0.69 V and Epa= -0 47 V（vs. SCE）. Various factors which affect the voltammetry of Eu（Ⅲ）-Calix-2Ar film electrode and the charge transport process of the electrode are discussed. Research showed that the voltammetry of the film electrode is affected by the concentration of supporting electrolyte ,the film thickness, solvent and the film has some properties of supramolecular system.展开更多
