In this study, poly(pyrrole), PPy, with hydrophilic property was coated on the surface of MWNT, subsequently, Pt-Ru alloy nanoparticles were deposited on PPy-coated MWNT by chemical reduction, r-irradiation, microwave irradiation, and ultrasonic irradiation, respectively. The Pt-Ru alloy nanoparticles were successfully confirmed on the PPy/MWNT composite by TEM, XRD, TGA and ICP analysis. The catalytic efficiency of Pt-Ru nanoparticle was determined to MeOH oxidation and CO adsorption ability. The catalytic efficiency prepared by ultrasonic irradiation method is the highest. |
