Constructing organic-inorganic semiconductor heterojunctions is an efficient way to inhibit the recombination of photogenerated charge carriers and enhance photocatalytic performance of semiconductor. Herein, a novel heterojunction antimony sulfide-perylene diimides (Sb2S3-PDI) heterojunction has been fabricated through a facile hydrothermal method. Compared with bare Sb2S3 and PDI, the Sb2S3-PDI hybrid has showed significantly superior activity in photocatalytic reduction of Cr (VI). The superior photocatalytic performance of Sb2S3-PDI hybrid is due to the formation of type-I heterojunction, which leads to a more efficient separation and migration of photogenerated electron-hole pairs. This work is expected to promote continued interest in the construction of organic-inorganic semiconductor composites with enhanced photocatalytic performance.
