Platinium-Ruthenium electrocatalyst as sensor electrode for methanol oxidation
Hybrid nanocomposites of binary Pt-Ru/Polyaniline were prepared by oxidative polymerization of aniline andformation Pt and Ru nanoparticles. The polymerization of aniline was carried out in the presence of Potassiumhexa cyano Platinate (IV) and Ruthenium (III) nitrosyl nitrate as oxidizing agents. During the reaction anilinemonomers undergo oxidation and form polyaniline (PANi) whereas the redu...
متن کاملKinetic study of ethanol and methanol electro-oxidation on Pd-vulcan XC-72R/Cu electrocatalyst in alkaline media
Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...
متن کاملSynthesis and characterization of Pt3Co bimetallic nanoparticles supported on MWCNT as an electrocatalyst for methanol oxidation
The impregnation method was used to synthesize Pt and Pt3Co supported on MWCNTs applying NaBH4 as the reducing agent. The structure, morphology, and chemical composition of the electrocatalysts were characterized through SEM, XRD, and EDX. X-ray diffraction showed a good crystallinity of the supported Pt nanoparticles on the composites and showed the formation of Pt3<...
