| 摘 要： | 光照TiO2表面产生强氧化性的活性氧基团,通过直接或间接的方式与细菌细胞结合,对环境微生物具有抑制或杀灭作用.与传统有机、无机抗菌剂相比,TiO2光催化杀菌具有持久、耐热、安全、不易产生耐药性、杀菌彻底等优点.另外,理论上光催化剂TiO2不消耗,可重复使用.主要介绍TiO2光催化剂的杀菌机理,及其在陶瓷、涂料、塑料、织物、水处理等领域的应用.并对TiO2抗菌材料的发展进行了展望.

| Abstract: | Reactive oxygen species generated on the surface of irradiated TiO 2 can combine directly or indirectly with microbial cell and then kill or inhibit microorganisms.Compared with traditional disinfectant,TiO 2 photocatalytic bactericide has the advantages of long duration,thermal resistance,safety,less drug-resistance,and high bactericidal activity.In addition,TiO 2 particles would not be consumed theoretically then could be used repeatedly.Progress of mechanism of photocatalytic bactericidal effect of TiO 2... |
