From xero to hero: The effect of different synthesis methods on the characteristics of PtRu catalysts supported on carbon xerogels is studied and methanol oxidation activity (expressed in terms of mass activity) is analyzed. The impregnation method and reduction with HCOOH renders the highest catalytic activity, owing to larger crystal sizes and more surface Pt. Catalytic activity results from the appropriate combination of crystal size and Pt/Ru atomic ratio.
