| 摘 要： | 采用水热法合成球形钛酸铋复合氧化物光催化剂，利用SEM、XRD和UV-Vis DRS等表征手段对复合氧化物的晶体结构、微观形貌和光学性能进行了分析，结果表明，制备的钛酸铋复合氧化物为10 nm的球形颗粒，具有良好的晶型结构，禁带宽度为2.7 nm，有较好的可见光吸收能力。以亚甲基蓝、甲基橙及酸性品红为目标污染物，研究了复合氧化物在可见光下的光催化降解有机污染物的性能，并对光催化降解机理进行了探讨。结果表明，在可见光照射下，该复合氧化物对酸性品红降解效果明显优于亚甲基蓝和甲基橙，光照150 min下，降解率可达91%。

| Abstract: | Spherical-like Bi4Ti3O12 composite was synthesized by hydrothermal method. The crystal structure, morphology and absorptivity of visible light were characterized by SEM, XRD, and UV-Vis spectrophotometer. The characterization results demonstrate that the Bi4Ti3O12 composite have good crystal form, structure and absorptivity of visible light. The photocatalytic activity of Bi4Ti3O12 composite was investigated by degradation methyl orange, methylene blue, and acid fuchsin. The results show that Bi4Ti3O12 composite exhibited significantly photocatalytic activity under visible light irradiation towards degradation of Acid fuchsin, and the degradation rate of Acid fuchsin can reach 91% after lighting 150 min by visible light. |
