Pt–ATO (Sb/SnO 2 ) nanoparticle is synthesized by the consecutive polyol process to enhance the catalyst activity for the oxygen reduction reaction (ORR) in the presence of methanol. Pt–ATO catalyst exhibits better activity for ORR with and without methanol than Pt black catalyst in a half-cell test, which could be attributed to the inhibition of the coagulation of Pt nanoparticles and partial...
This paper presents the effect of graphitic character of ordered mesoporous carbons (OMCs) on the performances of OMC supported catalysts for direct methanol fuel cells (DMFC). Two OMC samples with hexagonal mesostructure were prepared from phenanthrene and sucrose by nano-replication method using mesoporous silica as a template. Structural characterizations revealed that both OMCs exhibited large...
