Popis:	We report nanostructured supports prepared by heat treatment of TiO 2 nanoparticles at 700, 800, or 900 °C under ammonia atmosphere. From X-ray diffraction analysis, it is found that the phase transformation of the supports from antase and rutile TiO 2 , TiO to TiN (TiO 2 heated at 900 °C, TiO 2 -900) is observed. In particular, the Pt on TiO 2 -900 (Pt/TiO 2 -900) exhibits such an excellent catalytic activity toward methanol electrooxidation compared to the Pt on Vulcan XC-72. It is likely that enhanced catalytic properties of the Pt/TiO 2 -900 may be attributed to stability of nitride support and interaction between Pt catalyst and nitride support, which are confirmed by cycling test of supports and X-ray photoelectron spectra of Pt catalysts.
