摘　　要：稀土掺杂对TiO_2改性可以拓宽光谱响应范围、提高量子效率及太阳能利用率,是提高TiO_2纳米材料光催化活性及可见光吸收能力的重要方法。综述了近年国内外有关La掺杂TiO_2纳米材料的制备及光催化性能研究进展,主要分析了La掺杂材料的制备方法、物相特征以及La与其他元素共掺杂等方面的研究现状,并进一步指出La掺杂TiO_2目前存在的问题以及未来的研究方向。Rare-earth doped TiO2 can broaden the scope of spectral response and improve the quantum efficiency and solar energy utilization. It is an important improving method of the photocatalytic activity and visible absorption capacity for nano-TiO2 material. Base on the comprehensive literature review, the progress on preparation and photocatalytic properties of La-doped TiO2 nanomaterial were summarized. The research status of preparation method, the phase characteristics of La doped materials,and La codoped with other elements was mainly analyzed. The current problems and future research direc- tions of La-doped TiO2 were also discussed.
