摘要

ZnO/Bi2S3 composite based nanostructures were synthesized by varying Bi2S3 from 1 to 5 wt%, for the purification of wastewater. As-obtained catalytic nanomaterials were characterized by XRD, SEM, UV–vis and PL. XRD and SEM demonstrated the successful design of ZnO/Bi2S3 nanostructures-based composites, with tunable band gap while PL spectroscopy pointed to an enhanced charges separation rate, respectively. The photocatalytic activity of ZnO/Bi2S3 was investigated in the degradation of methylene blue (MB) and methyl orange (MO) dyes. ZnO/Bi2S3 composite with 4 wt% Bi2S3 (ZBS-4) exhibited optimum degradation efficiency (96% and 93%, respectively) against the model dyes. This composite material (ZBS-4) has shown improved kinetic rate constant values (0.0189 and 0.0182 min−1) against MB and MO dyes, respectively, with a solid stability and reusability even after 4-cycles of experiments.
