A room temperature approach for the fabrication of aligned TiO nanotube arrays on transparent conductive substrates

A novel solution approach is reported for the fabrication of TiO 2 nanotube arrays on transparent conductive substrates via in situ conversion from nanowires. The as-prepared nanotube arrays not only demonstrate a larger surface area in comparison with the primary NWs, but also longer charge carrier lifetime than that of randomly packed nanoparticle films. A novel room-temperature solution-approach is reported for the fabrication of highly crystallized TiO 2 nanotube arrays on transparent conductive substrates.
