Preparation of Nano-Composite Photocatalyst to Remove TOC in Power Plant Boiler Make-Up Water

Abstract:

A series of ZnO-TiO₂ nanocomposite photocatalysts were prepared to remove TOC in Power plant Boiler Make-up Water. The catalysts were prepared by solid-state method and characterized by the means of XRD, TEM and UV-Vis. Compared with pure TiO₂, the catalytic activity of the nanocomposite photo-catalyst was improved significantly. The experiment results show that the ZnO-TiO₂nanocomposite with ZnO/TiO₂molar ratios of 2:1 was the most efficient photocatalysts. Under the solar irradiation (3.5×10⁴ lux) for 5 h at pH 7.0, the photocatalytic effect could be as high as 92.6% and the TOC removal efficiency was 89.4%, which indicates that photodegradation and mineralization of HA are synchronous, the two results correlate well.
