摘要：

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