Platinum Nanoparticles Supported On Pristine Carbon Nanotubes For The Anodic Oxidation Of Methanol

Prinstine carbon nanotubes was dispersed by poly(3-hexylthiophene)-b-poly(vinylpyrrolidone). The poly (3-hexylthiophene) blocks attach to carbon nanotube surface through g- g interactions. Poly (vinylpyrrolidone) blocks stay at the outer surface of carbon nanotubes. Due to the high affinity of poly (vinylpyrrolidone) to platinum nanoparticles, platinum nanoparticles was loaded to carbon nanotubes through impregnation and reduction of Pt salt. The Pt nanoparticles distributed homogenously on carbon nanotube surface with particle size in the range of 2-4 nm. The carbon nanotube supported Pt nanoparticles can be applied as the catalyst in direct methanol fuel cells
