Electrospun PPO support with the mean fiber diameter 150 nm exhibited high porosity (80%) and suitable transport properties. Platinum and palladium catalysts were supported on electrospun nanofibers by the wet impregnation technique and subsequent activated by calcination in air at 175 °C. The catalytic activity of the prepared catalysts was tested in the total oxidation of methanol and ethanol in air as the model reactions. It was found the catalytic performance of electrospun catalysts depended linearly on the mean size of platinum nanoparticles. On the other hand, palladium catalysts exhibited the same catalytic performance irrespective of the varying mean Pd particle size. The different particle-size sensitivity of Pt and Pd catalysts was tentatively ascribed to the different nature of both noble metals.
