Competitive oxidation of CH3OH to CH2O occur via CH3OH → CH3O → CH2O vs. CH3OH → CH2OH → CH2O, further to COOH by the OH group via CH2O → CHO → CO + OH → COOH vs. CH2O + OH → CH2OOH → CHOOH → COOH, and finally oxidation to CO2 on Ru(0001).

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.
