纳米Black TiO_2的研究进展
|
摘要
利用太阳能从水中产生氢和去除环境中有机污染物的半导体光催化技术被认为是极具发展潜力的技术之一,其中TiO_2纳米材料被视为主要的光催化剂受到了重点研究,但高的光生载流子复合率和较宽的带隙导致其实际应用受到严重制约,通过制备在表面产生Ti 3+和氧空位缺陷的Black TiO_2有望解决这一问题。综述了Black TiO_2光催化材料的研究进展,并对其应用和发展前景进行了展望。
Semiconductor photocatalysis is considered to be one of the most promising technologies,which can use solar energy to generate hydrogen from water and remove organic pollutants from the environment.Among them,TiO_2 nanomaterials are regarded as the main photocatalysts,which have aroused focused investigation.Nevertheless,the high recombination rate of photon-generated carriers and wide band gap seriously restrict their practical application.It is expected that this problem will be solved by preparing Black TiO_2 with Ti 3+and oxygen vacancy defects on the surface.The research progress on the Black TiO_2 photocatalytic materials in recent years is reviewed.Some prospects and suggestions of the application and development of Black TiO_2 as photocatalytic materials are proposed.
