摘　　要：半导体光催化技术在太阳能转换以及环境治理方面具有巨大潜力。TiO_(2)由于其高的光催化效率、良好的稳定性以及合适的带边电位等,成为了当前研究最多的光催化材料。但TiO_(2)是宽带隙半导体,对可见光几乎不响应,这极大限制了TiO_(2)的应用。为了提高TiO_(2)对可见光的响应能力,提高太阳能的转化效率,相继开发了一系列由TiO_(2)衍生的Ti基可见光催化剂。首先简单地介绍了半导体光催化机制,然后综述了Ti基半导体光催化剂的分类、增强可见光响应策略以及Ti基可见光催化剂应用现状,最后总结了Ti基可见光催化剂制备及应用过程中所面临的挑战,同时也对未来Ti基可见光催化剂的合成及发展进行了展望。Semiconductor photocatalytic technique exhibits great potential in solar energy conversion and environmental governance.TiO_(2) is the most studied photocatalytic material at present because of its high photocatalytic efficiency,good stability and appropriate band edge potential.However,TiO_(2) is a wide band gap semiconductor and hardly responses to visible light,which greatly limits its application.In order to improve the response of TiO_(2) to visible light and enhance the conversion efficiency of solar energy,a series of Ti-based semiconductor photocatalysts have been developed.Firstly,the semiconductor photocatalysis mechanism was introduced.Then,the classification of Ti-based semiconductor photocatalysts,the strategies of enhancing visible light response and the application status of Ti-based visible light photocatalysts were reviewed.Finally,the challenges in the preparation and application of Ti-based visible photocatalysts were summarized.At the same time,the synthesis and development of Ti-based visible light photocatalysts in the future were also prospected.
