This book covers about carbon nanotubes, conductive polymer and nanocomposites as supporting material for electrocatalysts towards electrooxidation of alcohol in acidic medium. This book gives in-depth knowledge about CNT, conductive polymers and nanocomposite for electrooxidation alcohol at the anode compartment in the fuel cell device. This book gives clear information about preparation and characterization of conductive polymer, carbon nanotube and carbon nanotube-conductive polymer composites. Moreover, the experimental methods for co-deposition of alloy nanocatalysts and electrooxidations of alcohols in acidic medium were illustrated clearly.
