Photodegradation of Oily Waste Water Using Lanthanon-Doped TiO₂

Abstract

Nano-TiO2 with photocatalytic activity were prepared by sol-gel progress. Nd3+ and Tb3+ were adoped to enhance the photocatalytic activity. TG, DTG ,UV etc were used to character Nano-TiO2.From TG Nd restrains the growth of grain and the conversion of anatase to rutile.This improves the TiO2 heat stability. photo-degradation of oily waste water on titanium dioxide under Xe lamp was investigated.The reaction also features the photocatalytic activity of Nano-TiO2.The results indicate that Tb and Nd adoption have a positive effect on the photo-degradation.Lanthanon into titania could efficiently extend photoactivity and expand the visible light response range.
