dc.description.abstractInvestigating the novel Ti0.7Mo0.3O2 material can just as easily be used as a conductive support for PtRu for DMFCs to prevent not only the carbon corrosion but also improved activity of catalyst due to some functional advantages of novel Ti0.7Mo0.3O2 support. The Ti0.7Mo0.3O2 nanoparticle have good crystallinity with well-defined fringes corresponding to the 3.45 Å spacing value of the {101} plane of anatase TiO2, which were good according to the XRD pattern. The BET surface area measurements showed that the Ti0.7Mo0.3O2 possessed 125 m2 g-1 Fig. 3 shows the TEM measurement of Ti0.7Mo0.3O2 nanoparticle and Pt/Ti0.7Mo0.3O2, it can be observed that spherical PtRu alloy particles with an average particle size of 2-4 nm were uniformly anchored on the surface of Ti0.7Mo0.3O2 support. More importantly, we found that there has a strong metal support interaction (SMSI) between the PtRu noble metal and the Ti0.7Mo0.3O2 support material - resulting in facile electron donation from the Ti0.7Mo0.3O2 support to PtRu metal with an ultimate drastic decrease in the d-band vacancy of Pt.
