摘　　要：TiO 2作为一种高效、无毒、廉价且具有高稳定性的半导体光催化剂,在环境治理、空气净化、光解水制氢等领域受到研究者的广泛关注。但由于TiO 2的禁带宽度较宽,光量子产率低限制了其广泛应用。掺杂改性研究成为突破瓶颈的方式之一。稀土元素掺杂可以延迟锐钛矿相向金红石相转变,提高光催化性能。本文从稀土元素单掺杂、稀土元素与稀土元素共掺杂以及稀土元素与其他元素共掺杂等方面阐述了稀土掺杂TiO 2研究进展,并对未来稀土元素掺杂TiO 2的研究进行了展望。As a highly efficient,non-toxic,cheap and highly stable semiconductor photocatalyst,titanium dioxide has attracted extensive attention from researchers in the fields of environmental governance,air purification,photolysis water and hydrogen production.However,due to the wide band gap width of titanium dioxide,its wide application is limited by the low optical quantum yield.Doping modification has become one of the ways to break the bottleneck.Doping with rare earth elements can delay the transition from anatase to rutile and improve the photocatalytic performance.The research progress on rare earth doped titanium dioxide was described from the aspects of single doping of rare earth elements,co-doping of rare earth elements with rare earth elements and co-doping of rare earth elements with other elements,and the future research of rare earth doped titanium dioxide was prospected.
