摘要：

We have explored the nanocomposites as a potential catalyst material in acid medium for the electrooxidation of methanol. Electrochemical impedance studies have shown that the R-ct value of (Poly-3-Anisidine) P3A/GCE is lower than the modified P3A-metal oxide doped electrodes. In the case of doped metal oxides, we claim, this validates the slow electron transfer mechanism. Compared to P3A-MnO2, P3A-Fe2O3 catalysts, the as-synthesized P3A-Cr2O3 displays an expanded electrochemically active surface region, substantially enhanced catalytic activity and improved stability for methanol oxidation reaction (MOR).
