摘 要：Because of its good stability and conductivity,titanium nitride（TiN） is considered to be a very promising alternative support for Pt catalyst; however, the preparation of TiN supports is still challenging. In this work, atomic layer deposition was facilely adopted to fabricate TiN nanoparticles onto carbon nanotubes（CNTs）, and then the prepared TiN/CNTs hybrid was used as a support of Pt catalyst. The resulting TiN/CNTs-supported Pt nanoparticles（Pt@TiN/CNTs） nanocomposite showed higher catalytic activity and long-term stability toward the oxygen reduction reaction than the commercial Pt/C, which should be due to the high conductivity and high stability of TiN support, as well as the favorable Pt–TiN strong interaction.
