Abstract

Expanded perlite loaded titanium dioxide photocatalysts were prepared by a sol-gel method. Expanded perlites were modified using H₂SO₄ and cetyltrimethylammonium bromide in this experiment. The photocatalytic degradation mechanism of Reactive brilliant blue X-BR by expanded perlites loaded titanium dioxide photocatalysts has been investigated. The samples were characterized by scanning electron microscopy, specific surface area, X-ray diffraction analysis. The photocatalytic activities were evaluated by the photocatalytic oxidation of Reactive brilliant blue X-BR solution. It was found that the prepared expanded perlite loaded titanium dioxide photocatalysts have an excellent photocatalytic under ultraviolet illumination. The results of ultraviolet spectrum and infrared absorption spectrum showed that the anthraquinone structures and benzene rings were destroyed under photocatalytic oxidation reaction. The identification by gas chromatography-mass spectrometer analyses indicated that H₂O and carbon dioxide could be the primary degradation products.
