摘要
纳米二氧化钛光催化剂,由于其催化活性高、化学性质稳定、成本低、无毒等优点,已成为环境领域最有发展前景的光催化材料。针对其在催化过程中催化效率低、可见光利用率低、难回收利用等问题。本文综述了硅藻土负载纳米TiO_2负载方法及TiO_2掺杂改性最新研究进展,并提出了TiO_2光催化剂存在问题及发展前景。
Nano-TiO2 photocatalyst has become the most promising photocatalyst in environmental field due to its high catalytic activity, stable chemical properties, low cost, non-toxicity etc. In the catalytic process, there are these problems of low catalytic efficiency, poor visible absorption rate, and difficult to recycle. This paper reviews the method of diatomite loaded and doped nano-TiO2. The research prospect and some existing problems of nano-TiO2 Photocatalyst were discussed.
