Article Preview

Photoelectrocatalytic degradation performance of hexachlorobenzene (HCB) was assessed with a newly designed continuous photocatalytic reactor. CdS/TiO2 NTs were successfully prepared by depositing CdS particles on the surface of TiO2 nanotube arrays.The morphology, phase structure and photoelectric properties of CdS/TiO2 NTs were characterized by field emission scanning electron microscope, X-ray diffraction and diffuse reflectance spectroscopy. The photoelectrocatalytic activity of CdS/TiO2 NTs was evaluated in degradation of HCB in aqueous solution. The experimental results show that CdS/TiO2 NTs exhibited higher photoabsorption rate under visible light, bigger photocurrent (value) and improved photocatalytic activity than TiO2 NTs.
