Recent advances in modified TiO2 for 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 summarized the recent developments of TiO2-based materials in heterogeneous photocatalysis for organic synthesis. Generally, modified TiO2 shows enhanced photocatalysis with a narrow band gap or broad absorption spectrum. Based on the present work, the future perspectives of modified TiO2 photocatalysts for organic synthesis are presented.
