The TiO2-C hybrid material was prepared by carbonization of the mixed precursor containing TiO2 and urea, which was used to support Pt catalyst toward methanol electrooxidation. The Pt-TiO2-C hetero interfaces can be achieved with Pt nanoparticles deposited on the boundaries of rutile TiO2 and graphitic carbon of the TiO2-C substrate. The as-prepared Pt/TiO2-C catalyst possesses a large electrochemical surface area (ESA) and exhibited remarkably improved catalytic activity and stability toward methanol electrooxidation.
