In recent years, much progress has been obtained in enhancing the photocatalytic performance of non-TiO2 with rare earth elements doping. This paper analyzes and summarizes zinc-based , bismuth-based photocatalysts modified with rare earth elements by single-element doping or co-doping , oxide composite, upconversion photocatalysis and rare earth solid solution. Tungsten-based and other-based photoccatalysts modified with rare earth elements, and novel rare earth photocatalysts are introduced. The results show that rare earth elements modifications can affect lattice structure and band gap , broaden the scope of spectral response and improve quantum efficiency by increasing photocatalysis activity effectively. The application prospect of rare earth elements in photocatalysis is analyzed.
