Pt, Pt-Ru alloys and Pt-Ru-Mo alloys, decorat-ed on multi-walled carbon nanotube(MWCNT) by using flsh light irradiation as changing irradiation energy was investigated. Pt, Pt50-Ru50 and Pt47- Ru47-Mo6 alloys were coated on the MWCNT followed by flash light irradiation to form the nanoparticle alloy on MWCNT. The fabricated Pt based alloy nanoparticle/MWCNT were evaluated by X-ray diffraction(XRD), RAMAN spectroscopy and scanning electron microscope(SEM), respectively. From cyclic voltammetry(CV) study, it was found that Pt47-Ru47-Mo 6/MWCNT catalyst shows higher activity and stability for methanol electro oxidation compared to Pt/MWCNT and Pt50-Ru50/MWCNT one.
