摘要: Abstract In this research paper, we have constructed novel Z-scheme g-C3N4 nanosheet/MgBi2O6 systems with the visible light response for photocatalytic elimination of cationic pollutants such as MB, RhB, anionic CR, MO, and also colorless pollutant phenol. The batch tests illustrated that first-order kinetic constant amount-optimized nanocomposite gCN-NS/MgBi2O6 a mass ratio 70:30 was 1337.84 × 10−4 min−1 in degradation which 77.3-folds better than alone. Moreover, using various quenchers, scavenging test outcomes demonstrated ⦁OH, ⦁O2−, h+ remarkable role process. photostability system studied over four consecutive cycles revealing good reusability stability. Finally, according to energy band matching theory, mechanism charges movement offered boost different photoactivity. Our current work opens up new avenue further research.
