Environmental pollution is a significant global concern, and organic pollutants in water pose a significant threat to human health and the ecosystem. Photocatalysis has emerged as a promising technology for degrading organic pollutants in water due to its high efficiency, cost-effectiveness, and environmental friendliness. In this study, we investigate the efficacy of a novel heterojunction photocatalyst comprised of g-C3N4 and BiOCl in degrading organic pollutants in water. Among all the heterojunction photocatalysts, CN/B-2 demonstrated the best photocatalytic performance, outperforming both pure g-C3N4 and BiOCl photocatalysts. Using CN/B-2 as the photocatalyst of choice for RhB degradation, we were able to remove 93.87% of RhB, compared to a mere 34.96% removal efficiency when employing g-C3N4 alone. The improved performance can be attributed to the formation of the heterojunction photocatalyst, which broadened the absorption spectrum and increased charge carrier separation efficacy, as indicated by our various analyses.
