Bulk and Surface Compositions of PtRu Catalysts and Their Methanol Oxidation Activity and Durability

A controlled synthetic scheme of PtRu catalyst for methanol oxidation reaction is reported. PtRu catalyst was obtained by using an electroless plating method with chelate ligands. The well-mixed PtRu catalyst synthesized with chelate ligands (PtRu/C WCL) showed higher methanol oxidation reaction activity and stability relative to those of PtRu catalyst synthesized without chelate ligands (PtRu/C WOCL).
