ELECTROCATALYTIC PROPERTIES OF PLATINUM DOPED POLYANILINE AND POLYPYRROLE ELECTRODES

This review paper aims to show how the electrochemical behaviour of po lyaniline (PANI) and polypyrrole (PPy) electrodes modified by platinum help to improve the oxidation of organic molecules such as methanol, ethylene glycol and glucose. Although the amount of platinum deposited was very small, i.e., 0.1 mg.cm(-2), the catalytic activity obtained was comparable to bulk platinum. Another notable point is the reductio n of the poisoning effect, which is the main problem faced in the elec trooxidation of organic molecules for fuel cell applications.
