Recent advances on modified-TiO2 in photo-induced organic synthesis

Over the last decade, chemists have made great progress in photocatalysis. Compared with the well developed homogenous photocatalysis for organic synthesis, heterogeneous photoredox catalysis is still in its infancy. In this review, we took TiO2-based materials as an example and summarized the recent developments of TiO2-based materials in photocatalysis for organic synthesis. Generally, the modified-TiO2 shows an enhanced photocatalysis in narrow band gap or broad absorption spectrum. Based on the present works, the future perspectives of modified-TiO2 photocatalysts for organic synthesis are presented.
