Preparation and Photo-Catalysis Properties of Fe₃O₄/TiO₂ Nanocomposite

Abstract:

As a Kind of Most Common Used Photocatalyst, TiO₂ Nanomaterials Existing Disadvantages on Low Light Energy Utilization in Visible Light Range and Difficulty on Recycle. in Our Study, Different Proportions of Fe³⁺ and Fe²⁺ Ion Were Doped with Nano-Ti0₂ Particles in Structure of Rutile Type through Method of Chemical Precipitation. the Result Showed that Nano-Composites Formed by TiO₂ Coexist with Fe₃O₄, with the Average Size of the Composite Particles Nearly 20 Nm. the Photo-Catalyst Performances of the Composite Have Improved Largely, and so the Relatively Optimized Preparation Conditions Were Presented.
