Abstract
) exhibited the highest reactivity among the species tested. Calculations of band edge potential have verified that the Z-scheme charge transfer mechanism facilitates efficient charge separation and the generation of reactive oxygen species (ROS). Curiously, the pH of the heterogeneous composite was found to be correlated with its photocatalytic activity. An examination of the pH level disclosed a PZC value of 5.39. The composite functioned most effectively at a pH of 4. A novel CuS/CdS composite has been explored that is not only novel but is also ecological, cost-effective, and structurally stable in mineralizing the persistent azo dyes.
