    摘要:

    以乙酸鋅、錫酸鈉、氟化銨為原料,利用NH4F刻蝕,采用水熱法制備了尺寸250nm的空心結(jié)構(gòu)的ZnSn(OH)6立方體,通過(guò)X射線衍射(XRD)、紅外光譜(FTIR)、拉曼光譜(Raman)、掃描電鏡(SEM)、透射電鏡(TEM)、熒光光譜(PL)等來(lái)表征ZnSn(OH)6的晶體結(jié)構(gòu)、形貌和光學(xué)性能,通過(guò)降解亞甲基藍(lán)(MB)來(lái)探索不同水熱時(shí)間制備的ZnSn(OH)6的光催化性能。研究發(fā)現(xiàn),水熱2h制備的ZnSn(OH)6具有完整的空心結(jié)構(gòu),對(duì)甲基藍(lán)(MB)在可見(jiàn)光下降解效率為150 min降解97.4 %。說(shuō)明空心ZnSn(OH)6立方體光催化材料是一種具有前景的可見(jiàn)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.
