Synthesis of three-dimensional porous ZIF-67/Bi2S3 heterojunctions with improved photocatalytic activity under visible-light irradiation

A series of ZIF-67/Bi2S3 composites were successfully synthesized, and it was found that when the ZIF-67/Bi2S3 composite ratio was 40%, the efficiency of the binary composite was the highest, and the degradation rate of TCH reached 91.1%. The Type II degradation mechanism of ZIF-67/Bi2S3 composite photocatalyst was proposed.
