We report that electro-oxidation treatment of carbon paper generates specific functional groups, and controllable coating of metal oxide films on carbon surface alters capacitive behaviors. Electrochemical characteristics, I–V curves in fuel cells, and a structural analysis of XPS represent that the carboxyl group is the most effective functional group in an electro-oxidation of L-ascorbic acid. The appropriate film thickness of titania on electro-oxidized carbon electrode further increases… Expand
