Anatase TiO2 Nanospindle/Activated Carbon (AC) Composite Photocatalysts with Enhanced Activity in Removal of Organic Contaminant.

This paper embarks upon the three levels of analysis ranging fromnanoscale materials synthesis to combination and functionality. Firstly, we have prepared anatase TiO₂ nanospindles with an even length of about 200nm and a central width of about 25 nm by hydrothermal synthesis method at 100°C for 6 h. Secondly, we have dispersed TiO₂ nanospindles on the surface of activated carbon (AC) and fabricated TiO₂/AC composite via a dip-coating method. Thirdly, the TiO₂/AC composite has been studied as the photocatalyst to remove the organic contaminants in the waste water and exhibits excellent degradation rate in comparison with pure anatase TiO₂ nanospindles.
