Although many efforts have been done on the photocatalytic properties of anodic TiO 2 nanotubes, much less work is done on the photocatalytic performance of TiO 2 nanowires. Self-organized anodic TiO 2 nanowire arrays have been fabricated using a simple electrochemical approach and used as photocatalysts in photodegradation of methylene blue (MB) dyes. Here we found for the first time TiO 2 nanowires have better photocatalytic properties and incident photon-to-current efficiency (IPCE) than TiO 2 nanotubes. N doped TiO 2 nanowires showed further enhancement in photodegradation activity and photocurrent response in the visible region. Such TiO 2 nanowires are expected to have great potential in photodegradation of pollutants, photovoltaic solar energy conversion and water splitting for hydrogen generation as well.
