چکیده:

polyaniline fibers PANI were synthesized by chemical interfacial method and doped with para toluene sulfonic acid . The doped PANI was utilized for the fabrication of a vulcan -poilyaniline composite C-PANI . Pt and sn particles were subsequently deposited by reduction onto the C-PANI composite to produce a ptsn8:2 /C-PANI electrocatalyst .catalytic activity of this electrocatalyst is compared with ptRu/C. cyclic voltamettry studies in methanol oxidation reaction MOR show that the peak current density of ptsn8:2 /C-20%PANI is about 25% more than PtRu/c and its onset potential is about 100mV lesser moreover because of the presence of PANI fibers in catalyst support the methanol diffusion coefficient on this improved catalyst is 2 times more than pt Ru/c.
