摘要：

An inexpensive sol-gel technique to synthesize TiO2-Fe2O3 nanocomposites with improved structural and photochemical properties is introduced. A series of TiO2-Fe2O3 nanocomposites with different Fe2O3 contents were prepared through cheap TiO2 precursor titanium oxychloride (TiOCl2). The physicochemical properties of the samples were examined by XRD, XRF, SEM, EDX, HRTEM, UV-vis DRS, FTIR, TGA and nitrogen gas physisorption studies. The effects of calcination temperatures and Fe2O3 content on the mesostructure and photocatalytic strength of the prepared TiO2-Fe2O3 composites were investigated. Results showed that composites with distinct structural, optical and photochemical properties can be formed by varying Fe2O3 content.
