Synthesis of titanate nanofibers and nanotubes

A simple, mild and low-cost refluxing method was successfully used to synthesize titanate nanofibers and nanotubes. Properties of the as-prepared samples were characterized by means of TEM and XRD techniques. Optimization of the experimental conditions allowed, respectively, the preparation of titanate nanofibers and nanotubes. The photocatalytic activities of the prepared products were also investigated. The results indicated that titanate nanofibers and nanotubes had no photocatalytic activities for the degradation of methyl orange. Calcined at different temperature, the photocatalytic activities of the products increased, accompanying the change of structures.
