| 摘 要： | 采用溶剂热法合成了单斜白钨矿型钒酸铋（m-BiVO4）催化材料,采用XRD、BET、SEM、TEM等对其进行了表征。研究发现m-BiVO4的形貌和晶面可以通过反应溶液的pH进行调控,在pH=7条件下制备出了具有（010）晶面择优暴露的m-BiVO4（BVO-010）。以盐酸金霉素（CTC-HCl）、土霉素（OTC）、四环素（TC）和盐酸四环素（TCN）溶液为目标污染物,评价了制备材料的光催化降解性能。结果发现,与主要暴露热力学稳定的（-121）面的m-BiVO4（BVO-121）相比,BVO-010的降解性能明显提高,光照150 min后对CTC-HCl、OTC、TC和TCN的降解率分别为77.9%、79.2%、63.6%和73.9%,可用于处理含抗生素类药物的污水。

| Abstract: | The monoclinic scheelite bismuth vanadate（m-BiVO4） catalytic material was synthesized by a solvothermal method and characterized by XRD,BET,SEM,TEM,etc.It was found that the morphology and crystal facet of BiVO4 could be con-trolled by the pH value of the reaction solution,and m-BiVO4 with preferentially exposed（010） facet（BVO-010） was pre-pared at pH=7.With chlortetracycline hydrochloride（CTC-HCl）,oxytetracycline（OTC）,tetracycline（TC） and tetracycline hydrochloride（TCN） solutions as target pollutants,the degradation performance of the samples was evaluated.It was disclosed that compared to m-BiVO4 that mainly exposed the thermodynamically more stable（-121） facets（BVO-121）,BVO-010 ex-hibited more outstanding photocatalytic performance,and the degradation rates of CTC-HCl,OTC,TC,and TCN were 77.9%,79.2%,63.6%,and 73.9%,respectively after 150 min illumination,which was expected to treat wastewater containing antibiotic drugs. |
