Anatase/Bronze TiO2 Heterojunction: Enhanced Photocatalysis and Prospect in Photothermal Catalysis

TiO2 heterojunction with different TiO2 phases has been widely adopted for enhanced photocatalysis. Therein, a less common anatase/bronze TiO2 heterojunction, also named as anatase/TiO2(B) heterojunction, has recently drawn increasing interest. In this review, the structural advantages of anatase/bronze TiO2 heterojunction for enhanced photocatalysis is highlighted in terms of less lattice mismatch and better charge separation at the interface. Besides photocatalysis, the anatase/bronze TiO2 heterojunction is proven a promising candidate for heat-assisted photocatalysis, named as photothermal catalysis. Further, the anatase/bronze TiO2 heterojunction can serve as a good model to evaluate the strategy for improved photocatalysis and even photothermal catalysis. Herein, the recent attempts on boosting the photocatalytic and photothermal catalytic performance of anatase/bronze TiO2 heterojunction are summarized. It is expected that this review would arouse renewed interest for revisiting TiO2 heterojunction in photocatalysis, photothermal catalysis and other advanced photocatalysis.
