| 摘 要： | 以溶胶-凝胶法制备了掺杂稀土、Fe3+的TiO2,以其为催化剂氙灯条件下光降解含油污水,稀土、Fe3+掺杂后含油污水在可见光下降解率提高,Eu-TiO2在氙灯照射30min降解率可达88.87%,Ce-Fe-TiO2可见光下30min降解率可达到90.22%.

| Abstract: | Nano-TiO2 with photocatalytic activity were prepared by sol-gel method.RE3+,Fe3+were adoped to enhance the photocatalytic activity.The photo-degradation of oily waste water on titanium dioxide was investigated.The reaction also features the photocatalytic activity of Nano-TiO2.From the photocatalytic degradation RE3+,Fe3+doping TiO2could efficiently extend photo-response from UV to visible regions and improve the UV adoption.The percent degradation of oily waste water using Eu-TiO2and Ce-Fe-TiO2is 88.87%and 90.22%respectively under xenon lamp after 30min. |
