Synergistic effect of CuBi2O4/Bi2S3 dispersed over rGO layers for removal of toxic effluents photocatalytically

Abstract

Water pollution is the major issue to be resolved nowadays. To overcome water pollution, the use of nanotechnology proved to be an emerging field. In this project, CuBi 2 O 4 (CB-1) and Bi 2 S 3 (CB-2) were prepared by simple hydrothermal and chemical precipitation routes respectively. To enhance the effectiveness of the photocatalyst, the synthesis of CuBi 2 O 4 /Bi 2 S 3 (CB-3) and CuBi 2 O 4 /Bi 2 S 3 /rGO (CB-4) nanocomposite were carried out by ultrasonication method. Different physiochemical techniques were used to characterize the as prepared catalysts. The photocatalytic activity of fabricated catalysts was then checked for methylene blue degradation. Among all the samples, CB-4 showed the best photocatalytic performance (90.47 %) as it has low band gap energy than other fabricated materials. Therefore, the fabricated nanocomposite can be employed as a promising photocatalytic material for future use.
