The samples will be synthesized by sol-gel method, and characterized by multiple techniques to evaluate their structures, morphologies, optical properties, and photocatalytic activities. The expected results will provide theoretical basis and experimental evidence for improving the photocatalytic performance of TiO2 materials.Keywords: TiO2; Graphene; Fe3+ modification; Synthesis; Photocatalytic activity.
