Pt-TiO_2 nanotubes with tube diameter of ~120 nm and uniformly dispersed Pt particles(size of ~2 nm) were successfully synthesized via a carbon nanotube(CNT) templating method followed by a photo-deposition processing of Pt nanoparticles. The as-obtained Pt-TiO_2 NTs possess both enhanced visible light absorption and reduced recombination of photogenerated electrons and holes. These merits boost the Pt-TiO_2 NTs an excellent photocatalytic material toward photooxidation of a variety of low molecular hydrocarbons under atmospheric environment.
