| 摘 要： | 通过水热法制得磷修饰氧化钛,它在亚甲基蓝和对氯苯酚的降解以及消除大肠杆菌的实验中都表现出高于纯氧化钛的优异活性,甚至优于商品化催化剂P25.在捕获剂中降解亚甲基蓝的实验证实羟基自由基是最主要的活性氧物种,并且磷修饰氧化钛在光照下拥有较强的产生羟基自由基的能力,同时,磷修饰氧化钛具有非常高的热稳定性,直到950℃才会发生...

| Abstract: | The phosphorous-modified TiO2(P-TiO2) was synthesized by a hydrothermal method. The as-prepared P-TiO2 was evaluated for the degradation of methylene blue,the dechlorination of 4-chlorophenol,and the inactivation of Escherichia coli. In all these experiments,P-TiO2 shows superior activity compared with pure TiO2 and even better activity than the commercially available P25 in most cases. By carrying out methylene blue degradation in the presence of different scavengers,OH radicals were found to be the domina... |
