【摘要】 TiO₂作为一种成熟的半导体材料,具有无毒、无污染、成本低且氧化能力强的特点,被认为是极具开发前景的光催化材料,研究其改性方法,有助于充分发挥其在处理含抗生素废水方面具有的降解彻底、无二次污染、反应温和、使用范围广等优势。文章阐述了TiO₂光催化的机理,对近年来国内外广泛使用的金属元素掺杂、非金属元素掺杂、共掺杂、贵金属沉积改性、材料复合改性、结构和形貌调控等方法进行了综述,分析了以不同改性方法制备的TiO₂功能光催化剂在净化抗生素废水时的效果,并对TiO₂光催化技术在抗生素废水处理中的应用进行了展望。更多还原

【Abstract】 As a mature semiconductor material,TiO₂ has the characteristics of non-toxic, pollution-free, low cost and strong oxidation ability, which considered as a promising photocatalysis material. The study of its modification method is helpful to exert the advantages in the treatment of antibiotic wastewater, such as complete degradation, no secondary pollution, mild reaction, widely apply and so on. In this paper, the methods including doping metal, doping non-metal, co-doping, nobal metal deposition, material composite, structure and morphology control and so on, which are widely used at home and abroad in recent years, are summarized. The effect of TiO₂ photocatalysts prepared by different modification methods in purifying antibiotic wastewater is compared, and the application of TiO₂ photocatalysis technology in antibiotic wastewater treatment is prospected.更多还原
