摘要：
A comparative study of the electro-oxidation of ethanol and 2-propanol was carried out on carbon-supported platinum particles. Cyclic voltammetry, steady state polarisation, and electrochemical impedance spectroscopy were used to investigate the oxidation reactions. A difference in the mechanistic behaviour of the oxidation of ethanol and 2-propanol on Pt was observed, thereby highlighting the fact that the molecular structure of the alcohol has great influence on its electroreactivity. The study emphasizes the fact that 2-propanol is a promising fuel candidate for a direct alcohol fuel cell.
