摘要
采用水热合成法制备出氟掺杂膨润土负载锡酸钙复合光催化剂,采用X射线衍射(XRD)、扫描电子显微镜(SEM)等分析手段对样品的形貌和结构进行了表征,并在可见光条件下考察了催化剂用量、氟掺杂量、反应时间等因素对复合光催化剂降解亚甲基蓝废水溶液性能的影响。结果表明:氟掺杂量为0.04%(质量分数)时复合光催化剂对亚甲基蓝溶液的降解效果最好,当催化剂质量浓度为60 mg/L,反应时间为13 min时,其对亚甲基蓝溶液的降解率可达98.6%。
Fluorine/bentonite/CaSnO3 composite photocatalysts were prepared by hydrothermal synthesis method.The morphology and structure of samples were characterized by X-ray diffraction（XRD） and scanning electron microscope（SEM）etc..The effects of light catalyst dosage,fluorine-doping ratio,and reaction time on photocatalytic activity of methyl blue waste water were also investigated.Results indicated that the photo-degradation efficiency could reach 98.6% when the fluorinedoping ratio was 0.04%（mass fraction）,the mass concentration of photocatalyst was 60 mg/L,and the reaction time was 13 min.
