Progress of Synergistic Effect of Nanomete SnO2 to Pt Electocatalysts Toward Methanol Oxidation Reaction in Acid Electrolyte
Tin dioxide nanoparticles were prepared through the Sol-Gel method and were mixed with Pt black catalysts physically for Pt-SnO2/C which was synthesized by dipping-reduction method;Surface morphology and composition of the resulting electrocatalysts were studied by means of XRD,The electrochemical catalytic activity of the working electrode prepared Pt-SnO2/C was tested by cyclic voltammetry in acidic medium.The results showed that Tin dioxide can improve the catalytic oxidation of methanol by Pt catalyst.
