It wasfound that the catalytic effects depend mainly on the size and amounts of the platinummicroparticles dispersed in the polymer layer.展开更多

Changes in the electrode rotation rates (Ω) during platinum electrodeposition remarkably affect the formation and distribution of platinum in the polymer matrix and consequently lead to different currents of methanol oxidation. The results show that platinum loading is proportional to rotation ratesΩ1/2.展开更多
