    Abstract:

    ZnSn(OH)6 cubes with the hollow structure of 250 nm in size were prepared by hydrothermal method with zinc acetate , Na2SnO3 and ammonium fluoride as raw materials using NH4F etching. The crystal structure, morphology, and optical properties of ZnS(OH)6 were characterized by X-ray diffraction (XRD), infrared spectroscopy (FTIR), Raman spectroscopy (Raman), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Photoluminescence (PL). The photocatalytic properties of ZnSn(OH)6 prepared at different hydrothermal reaction duration were investigated by degrading methylene blue (MB). It was found that ZnSn(OH)6 prepared by hydrothermal treatment for 2 h had a complete hollow structure, and its degradation efficiency of methyl blue (MB) was 97.4 % in 150 min under visible light. The hollow ZnSn(OH)6 cubic photocatalytic material is a promising photocatalytic material for visible light degradation.
