NOVELTY - The preparation of graphene/palladium nanocatalyst by photoreduction of phosphotungstic acid, involves mixing mixture of phosphotungstic acid and isopropanol with graphene oxide solution to obtain mixed solution, ultrasonically mixing the mixed solution and chloropalladic acid solution, irradiating under UV lamp to obtain direct alcohol fuel cell electrocatalyst, centrifuging and carrying out electrochemical test of product obtained by centrifugation. USE - Preparation of graphene/palladium nanocatalyst used in direct alcohol fuel cell. ADVANTAGE - The method enables preparation of graphene/palladium nanocatalyst with high alcohol catalytic activity by simple and easy process, and simultaneously reduces graphene and palladium nanoparticles.
