A floating composite photocatalyst of hollow glass microspheres (HGM)/ZnIn2S4/α-Fe2O3 was prepared by a modified hydrothermal method. The HGM/ZnIn2S4 composite was firstly prepared with HGM as a carrier, and then further modified with nanorod-shaped α-Fe2O3 to obtain the floating composite photocatalysts of HGM/ZnIn2S4/α-Fe2O3. The effects of α-Fe2O3 content, photocatalysts addition and solution pH value on the photocatalytic activity of the composite photocatalysts for the degradation of hexavalent chromium (Cr6+) were investigated. The results show that α-Fe2O3 and hexagonal ZnIn2S4 heterogeneous structure are formed, and the composite photocatalyst is uniformly loaded on the surface of HGM. Compared to α-Fe2O3 powder and HGM/ZnIn2S4 composite microspheres, the photocatalytic performance of HGM/ZnIn2S4/α-Fe2O3 is improved. The prepared composite photocatalyst still has a good photocatalytic efficiency after several recycling. In addition, the synthesis mechanism of HGM/ZnIn2S4/α-Fe2O3 and its enhanced photocatalytic mechanism were also discussed.
