    摘要:

    以乙酸锌、锡酸钠、氟化铵为原料,利用NH4F刻蚀,采用水热法制备了尺寸250nm的空心结构的ZnSn(OH)6立方体,通过X射线衍射(XRD)、红外光谱(FTIR)、拉曼光谱(Raman)、扫描电镜(SEM)、透射电镜(TEM)、荧光光谱(PL)等来表征ZnSn(OH)6的晶体结构、形貌和光学性能,通过降解亚甲基蓝(MB)来探索不同水热时间制备的ZnSn(OH)6的光催化性能。研究发现,水热2h制备的ZnSn(OH)6具有完整的空心结构,对甲基蓝(MB)在可见光下降解效率为150 min降解97.4 %。说明空心ZnSn(OH)6立方体光催化材料是一种具有前景的可见光催化降解材料。

    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.
