摘要
Fe3+-doped TiO2/diatomite composite photocatalyst were prepared by sol-gel method with titanium isopropoxide used as precursor material. The samples were characterized by SEM, XRD, XPS, BET surface area analysis and UV-Vis techniques. The results showed that the optimum concentration of Fe3+ in the composite catalyst was 0.2wt% when the quantity of TiO2 loaded on the diatomite was 30.3wt%. Compared with the un-doped photocatalyst, the Fe3+-doped sample exhibited red shifts of absorption edge and significant enhancement of light absorption at 400 similar to 600 nm.
