Pt, Pd and Pt-Pd nanoparticles (NPs) were synthesized on carboxylic graphene (CGR) sheets. The nanocomposites were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectra (FTIR) and UVvis absorption spectroscopy. Their electrocatalytic activity for methanol oxidation was also investigated. The results showed the peak current density of methanol oxidation of Pt NPs-Graphite oxide (GO), Pd NPs-CGR, Pt NPs-CGR and Pt-Pd NPs-CGR is 12.2μA/cm2, 14.1μA/cm2, 15.1μA/cm2and 21.5μA/cm2respectively. The nanocomposite of CGR as catalyst supports and Pt-Pd NPs as catalyzers is promising for direct methanol fuel cells.

A novel Pt–CoP/C electrocatalyst was developed for direct methanol fuel cells. This catalyst showed superior power density to commercial Pt/C and PtRu/C catalysts. In situ ATR-SEIRAS technology revealed that the presence of CoP in the Pt-based catalyst can promote the methanol oxidation to final CO2 products.
