Electrocatalysis and related factors of platinum microparticles dispersed on/in polypyrrole film in methanol oxidation

Platinum microparticles display effective electrocatalysis for methanol oxidation in 1 M MeOH+1 M HClO4 and polypyrrole film exhibits a promotive action for such electrocatalysis. The electrocatalytic activity is determined by the loading mass of the platinum microparticles, and the potential and medium used for the electropolymerization of PPy film. The thickness of the polypyrrole film under the chosen experimental conditions is less critical …
