Abstract

TiNC nanostructure supports consist of TiN as a core prepared at 900 degree C in NH3 and carbon as a shell by heat treatment of the TiN at 900 degree C in CH4 for 1, 3, and 6 h (referred as TiNC-1 h, TiNC-3 h, and TiNC-6 h). The thickness of the carbon shell layers in the TiNC supports increase with increasing reaction time at 900 degree C in CH4. In particular, the TiNC-1 h supported Pt catalyst exhibits much improved electrocatalytic properties toward methanol electrooxidation as compared to Pt catalysts on Vulcan XC-72R.
