Effect of the Ce-TiO₂/Diatomite on the Photo-Catalysis Degradation of MB

Abstract:

In this paper, TiO₂/diatomite and Ce-TiO₂/diatomite were prepared by sol-gel method in order to improve the spectrum responding range and its photocatalytic effect. The obtained samples were characterized by means of X-ray Diffractometer (XRD), Scanning Electron Microscope (SEM), Infrared Absorption Spectroscopy (FT-IR) and so on, and the photocatalytic activity was evaluated by methylene blue degradation. The heat stability of TiO₂/diatomite was improved by Ce-doped; TiO₂ was successfully loaded on diatomite through physical and chemical action. The de-coloring ratio of methylene blue of the two composite materials were similar under UV light, Ce-TiO₂/diatomite was higher under visible light, it reached to 80%, and it kept 65% after the five times repeated using of Ce-TiO₂/diatomite.
