Degradation efficiency of MB under different (a) dosage nanocomposite, (b) MB concentrations, (c) NH₄PDS concentrations, (d) solution pH, (e) different catalysts, and (f) various AOP methods. Experimental conditions unless otherwise specified: [catalyst] = 0.5 g L^− 1, [NH₄PDS] = 0.5 g L^− 1, MB = 20 mg L^− 1). The analytical measurements demonstrate a reproducibility of less than 3% based on triplicate runs. The experimental conditions mentioned above were applied to all figures.
