稀土、Fe^(3+)掺杂TiO_2可见光降解含油污水

Photodegradation of Oily Waste Water Using Rare-earth,Fe^(3+) Doped TiO_2 under Irradiation by Visible Light

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%.

Nano-TiO_2 with photocatalytic activity were prepared by sol-gel method. RE^3＋ , Fe^3＋ 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-TiO_2. From the photocatalytic degradation RE3＋ , Fe^3＋ doping TiO_2 could efficiently extend photo-response from UV to visible regions and improve the UV adoption. The percent degradation of oily waste water using Eu-TiO2 and Ce-Fe-TiO_2 is 88.87 % and 90, 22 %respectively under xenon lamp after 30 min,
