Preparation and Photocatalytic Performance of Fe3O4@H-TiO2—Experimental Research and Dynamic Model

Abstract

In this experiment, the preparation method and photocatalytic properties of H-TiO₂ composite catalyst were studied. In this reaction, Fe₃O₄ was selected as the carrier of the catalyst. In this experiment, titanium tetraisopropoxide was used as the titanium source to synthesize H-TiO₂, and then NaBH₄ was used to reduce titanium dioxide to prepare hydrogenated titanium dioxide. In this experiment, the co-precipitation method was used to prepare the composite Fe₃O₄@H-TiO₂ photocatalyst, and the magnetic inspection of the composite catalyst was performed. In this experiment, the photocatalytic degradation curve of the composite photocatalyst Fe3O4@H-TiO2 under ultraviolet lamp and simulated sunlight was studied. According to the amount of photocatalyst, the kinetic equation of Fe₃O₄@H-TiO₂ photocatalyst with different qualities was studied, and the kinetic model of Fe₃O₄ @H-TiO₂ photocatalyst was studied.
