Fig. 7: Degradation performance of the fabricated photocatalysts at various reaction conditions.

Effect of contact time on the photodegradation of (a) ofloxacin and (b) para-nitrophenol; (c) degradation performance by various catalyst combinations; COD analysis for the degradation of (d) ofloxacin and (e) para-nitrophenol; (f) degradation performance of Cd/CdIn2S4@Ch quantum dots on various other pollutants; Reaction conditions: OFL/PNP concentration—20/15 ppm; catalyst dosage—10/12 mg; pH—7/3; H2O2 dosage—0.2/0.3 mL. Error bars represent the standard deviations.
