Outline of Final Research Achievements

CO pulse adsorption experiment suggested that the cause of the high activity of PtRu/TECNF catalyst for methanol oxidation reaction is CO spillover from the noble metal surface to the support. TCCNF obtained by oxidizing the TiO2 precursor dispersed on the CNF surface and CeO 2 embedded CNF have been proposed as catalyst support of PtRu nanoparticles as an alternative support of TECNF. It was found that the catalyst layer of PtRu/TECNF becomes thick with a higher porosity than that in the case of PtRu/C. The optimum content of PtRu in PtRu/TECNF was 30 wt%, and the DMFC using it was far higher than the commercially available catalyst of 174 mW/cm2.
