Gas-Supported High-Photoactivity TiO2 Nanotubes

الملخص EN

By changing hydrothermal condition and post-heat-treatment temperature, silica-coated TiO2 nanotubes are obtained successfully.

The effects of gas-supported process on tubular morphology, crystallinity, and photocatalytic activity are discussed.

It is found that the sample prepared at hydrothermal treatment (180°C/9 h) and calcination (650°C/2 h) shows perfect open-ended tubular morphology and increased crystallinity.

The photoactivity of the sample is proved to be 5 times higher than that of TiO2 nanoparticles.
