A mesostructured composite catalyst, Pt–SnO 2 supported on graphitized mesoporous carbon (GMC), has been prepared and its electrochemical activity for methanol oxidation has been investigated. The materials were characterized by XRD, FESEM, TEM, EDX spectrum and N 2 sorption techniques. Cyclic voltammetry, chronoamperometry and steady-state polarization tests were adopted to characterize...
