Outline of Final Research Achievements

In this study, developments of composite catalysts with the interaction between intermetallic compound-metal oxide-carbon. The composite catalyst, PtPb (intermetallic compound) supported on titanium oxide embedded carbon nanofiber (TECNF), was prepared. Ethanol electrooxidation activity for PtPb/TECNF, Pt/TECNF, Pt/C (commercial catalyst) was measured. The mass activity at 0.70 V vs. RHE for PtPb/TECNF was almost six times higher than that for Pt/C. The anti-CO property by the interaction for PtPb/TECNF was suggested by CO stripping measurement. The power density of a direct ethanol fuel cell for PtPb/TECNF was higher than that for Pt/C.
