摘要
碘氧铋(BiOI)是一种新型光催化剂,以硝酸铋(Bi(NO3)3)、碘化钾(KI)为原料,分别采用水热法以及溶剂热法制备两种形貌的BiOI材料,通过X射线粉末衍射仪(XRD)、扫描电子显微镜(SEM)、红外光谱(FTIR)、紫外可见漫反射(UV-Vis DRS)和N2 吸脱附测试仪对其进行形貌、结构、性能表征.以四环素(TC)水溶液为例,测试制得的BiOI光催化降解性能,重点考察材料结构、光照条件、双氧水(H2O2)协同作用等对降解性能的影响.实验结果表明,溶剂热法制备的BiOI和H2O2协同作用时,在模拟太阳光下对四环素降解效果最好,4 h降解率可达 99.11%.
Abstract
Bismuth iodide(BiOI)is a new type of photocatalyst.In this paper,bismuth nitrate(Bi(NO3)3)and potassium iodide(KI)were used as raw materials,and two morphologic BiOI materials were successfully prepared by hydrothermal method and solvothermal method,respectively.The morphology,and structure were characterized by X-ray powder diffractometer(XRD),scanning electron microscope(SEM),infrared spectroscopy(FTIR),UV-Vis diffuse reflection(UV-VIS DRS)and N2 adsorption desorption tester.Tetracycline(TC)aqueous solution was taken as an example to test the photocatalytic degradation performance of BiOI prepared.The influences of material structure,light conditions and the synergistic effect of hydrogen peroxide(H2O2)on the degradation performance were mainly investigated.The results showed that the BiOI prepared by solthermal method had the best tetracycline degradation effect the under simulated sunlight,and the degradation rate reached 99.11%in 4 h.
