摘要：
The latest development of nanoscience has created new opportunities for the construction of SnO2-based composite materials as efficient photocatalysts. In this work, we first proposed a simple method to prepare ZnIn2S4/SnO2 photocatalyst by electrospinning and solvothermal methods. The absorption wavelength range of the modified SnO2 nanotubes can be extended from UV to visible light. Compared with traditional SnO2-based composite materials, the network structure can enhance the photocatalytic activity, which may be caused by the intimate contact between hollow SnO2 nanotubes and ZnIn2S4 nanosheets. The construction of ZnIn2S4/SnO2 heterostructure improved the separation efficiency of photogenerated electrons and holes, and Cr(VI) was completely removed within 80 min. Finally, the photocatalytic mechanism of ZnIn2S4/SnO2 composite was described in detail. (C) 2020 Elsevier B.V. All rights reserved.
