| Abstract: |
| A photocatalytic composite material of floating beads@nitrocarbon (P@C3N4) was prepared. The performance of material was characterized by XRD, SEM, XPS and UV-dis. Degradation effect and kinetics of methylene blue (MB) and tetracycline using P@C3N4 as catalyst under visible light was investigated. The reusability and degradation mechanism of composite materials were discussed. The results show that C3N4 is successfully loaded on fly ash float beads, and P@C3N4 composite material exhibites excellent visible light absorption performance. P@C3N4 composite material can effectively improve degradation effect of MB and tetracycline under visible light, and the first-order kinetic model can express the photocatalytic degradation process of pollutants. P@C3N4 photocatalyst has highly stability, and holes and hydroxyl radicals are likely to be the active species playing a major role in the process of photocatalytic reaction. |
