摘　　要：二氧化钛作为一种低成本、高效能的光催化剂,广泛应用于工业,但禁带宽度大、可见光下利用率低等局限性限制了其光催化活性的进一步提升。综述了金属与金属共掺杂、非金属与非金属共掺杂以及非金属与金属共掺杂在可见光响应下分别对纳米二氧化钛光催化剂催化性能的影响,分析各类情况的优劣势,总结最佳掺杂情况,为进一步实验研究提供可行性选择,在此基础上提出面临的问题并加以展望。As a low-cost and efficient photocatalyst,titanium dioxide is widely used in industry. However,due to the wide band gap and low utilization under visible light,the further improvement of photocatalytic activity is limited. The effects of metal to metal co doping,non-metal to non-metal co doping and non-metal to metal co doping on the catalytic performance of nano-TiO_(2) photocatalyst under visible light response were reviewed,the advantages and disadvantages of various situations were analyzed,and the best doping situation was summarized.This review provides feasibility options for further experimental research and presents problems and prospects.
