| 摘 要： | 以B(iNO)3·35H2O和T(iSO)42为反应物,用异丙醇助水热法制备了钛酸铋光催化剂,并研究不同水热温度和水热时间对样品光催化活性的影响。用XRD表征了样品的结构,UV-vis漫反射测试显示含有Bi12TiO20的样品的吸收带发生了红移,BET测试表明样品的比表面积远远高于化学溶剂分解法制备的钛酸铋的比表面积。以甲基橙为模拟污染物,评价了样品的光催化性能,发现当水热反应温度为140℃,水热反应时间为2.5h时,样品的光催化活性最高,且超过P25。

| Abstract: | Photocatalyst of bismuth titanate was synthesized by using B(iNO)33.5H2O and T(iSO)42 as reactants via an isopropanolassisted hydrothermal method,the influence of different hydrothermal temperatures and different hydrothermal times were studied. The structures of samples were characterized by XRD,and UV -vis absorption spectra results revealed that the samples containing Bi12TiO20 red-shifted,BET testing result showed that surface area of as-prepared sample was higher than that prepared by chemical solution... |
