Promoting Effect of Chemical Self-Assembled Polyaniline Nanofibers and Electro-Polymerized Polyaniline in Formic Acid Electro-Oxidizing Reaction

In order to enhance catalytic properties of palladium or gold/palladium alloy on polyaniline surface, highly pure PANI nanofibers doped with phosphoric acid were synthesized via chemical self-assembled method. Its general morphology was observed by scanning electron microscopy analysis. The deposition of palladium or gold/palladium alloy on PANI nanofibers was accomplished through reducing reaction of PdCl2 or PdCl2/HAuCl4 in aqueous solution by NaBH4. Pd/PANI nanofibers or Au/Pd/PANI nanofibers have been evaluated for catalytic activity toward formic acid oxidation reaction. Palladium/PANI nanofibers or palladium/gold/PANI nanofibers on glass carbon electrodes exhibit effective electro-catalytic activity since the PANI nanofibers play excellent promoting role.
