Zeolite Supported-Nano TiO2 Composites Prepared by a Facile Solid Diffusion Process as High Performance Photocatalysts
In this paper, zeolite supported-nano TiO2 photocatalytic composites were synthesized by an easily-operated solid diffusion process, in which zeolite was used as the support matrix. And the microstructures, morphologies and photocatalytic properties of the zeolite supported-nano
TiO2 composites were characterized and analyzed by scanning and transmission electron microscopy, X-ray photoelectron spectroscopy, UV-visible spectroscopy, fluorescence spectroscopy and methylene blue degradation tests. The results showed that zeolite matrix reduced agglomeration
of nano-TiO2 and enhanced the absorption ability within the UV-Vis range, consequently increased the photocatalytic activity of the composites. Meanwhile, the influences of TiO2/zeolite proportion on their photocatalytic performances were explored, which indicated that
90 wt% TiO2/zeolite had optimal photocatalytic capability and stable properties.
