摘要：
In recent years, limited photocatalysis efficiency and wide band gap have hindered the application of TiO2 in the field of photocatalysis. A leading star in photocatalysis has been revealed as lead-free Cs2AgBiBr6 double halide perovskite nanocrystals, owing to its strong visible light absorption and tunable band gap. In this work, this photocatalytic process was facilitated by a unique TiO2/Cs2AgBiBr6 composite, which was identified as an S-cheme heterojunction. TiO2/Cs2AgBiBr6 composite was investigated for its structure and photocatalytic behavior. The results showed that when the perovskite dosage is 40%, the photocatalytic rate of TiO2 could be boosted to 0.1369 min-1. This paper discusses and proposes the band gap matching, carrier separation, and photocatalytic mechanism of TiO2/Cs2AgBiBr6 composites, which will facilitate the generation of new ideas for improving TiO2's photocatalytic performance.
