摘要
利用低温液相沉淀法制备BiOI/ZIF-8复合光催化剂,同时研究ZIF-8复合量对催化活性和反应动力学的影响,采用X射线衍射(XRD)、高分辨透射电镜(HRTEM)、紫外-可见漫反射(UV-Vis DRS)等研究手段对样品进行表征。通过在可见光下降解甲基橙(MO),对其光催化性能进行评价。结果表明,BiOI/ZIF-8复合光催化剂具有较好的光催化性能,并且当复合量为3%时复合材料光催化降解性能最好,可见光照射60 min后对质量浓度为40 mg/L的MO溶液的降解率达到99.5%。
Bismuth iodide/Zeolite imidazole skeleton-8(BiOI/ZIF-8)composite photocatalyst was prepared by low temperature liquid phase precipitation method and the effect of the amount of ZIF-8 on the catalyst activity and reaction kinetics was discussed.X-ray diffraction(XRD),high resolution transmission electron microscopy(HRTEM)and UV-Vis spectrophotometry were adopted to analyze the structure and morphology of the samples.The photocatalytic activity of the prepared catalysts was used for the degradation of methyl orange(MO)under visible light.The results show that the BiOI/ZIF-8 composite photocatalyst has a good photocatalytic performance.When the amount of ZIF-8 is 3%,the composite photocatalytic material shows the highest photocatalytic activity under visible light,and the degradation rate of methyl orange(40 mg/L)reaches 99.5%after 60 min.
