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.

Electrooxidation Of Methanol

A new approach of spontaneous deposition was carried out to prepare the Ru/Pt film electrocatalyst for direct methanol fuel cells. This deposition method just made Pt like a ‘skin’ covered Ru films, which reduced the load of Pt but obtained a higher activity. The Pt-modified Ru films electrode was studied with the cyclic voltammetries and in-situ ATR-SEITA spectra on methanol oxidation. Compare to bare Ru and Pt, the bands of the adsorbed CO and water observed in IR spectra can be assigned. The present results give a clue for designing new electrocatalysts for DMFCs.
