Currently, slow anode kinetics hinders the development of the direct methanol fuel cell. Understanding of the reaction mechanism and rate-limiting step is required to search for the better anode catalysts. Based on the bifunctional mechanism of methanol electrooxidation and on electronic model (the ligand effect), the addition of two oxophilic elements (Ru and Os) to Pt is studied. Methanol oxidation mechanism is studied on Pt, PtRu and PtRuOsIr using isotope labeling. The results show that water activation controls the electro-oxidation of methanol at low potentials and that C-H bond scission becomes important at more positive potentials.Subjects--Topical Terms:
