| 摘 要： | 以硝酸铋、碘化钾和十六烷基三甲基溴化铵(CTAB)为原料,钙基蒙脱石为载体采用水热法合成了具有可见光响应的蒙脱石负载型BiOI/BiOBr异质结光催化剂。采用SEM、XRD、FT-IR、UV-Vis DRS等表征方法对其组成、晶型、形貌和光学吸收性能进行了研究。以有机染料罗丹明B(RhB)为目标降解物,考察了合成的负载型异质结催化剂的光催化活性,并初步探讨了其光催化性能提高的机理。

| Abstract: | A heterojunction photocatalyst,montmorillonite-supported BiOI/BiOBr with visible light response,was synthesized by hydrothermal method using bismuth nitrate,potassium iodide and cetyltrimethylammonium bromide(CTAB)as raw materials and calcium-based montmorillonite as a carrier.The composition,crystalline,morphology and optical absorption properties of the samples were studied by means of SEM,XRD,FT-IR and UV-Vis DRS,res-pectively.The photocatalytic activity of the synthesized supported heterojunction catalyst was investigated using Rho-damine B(RhB)as the degradation object.The mechanism of the improved photocatalytic activity of the photocataly-sts was also preliminarily discussed. |
