| 英文摘要 | Developing environmental friendly catalysts with efficient photocatalytic activity plays an important role in the area of water purification. In this study, metal free perylene imide-carbon nitride (PI-g-C3N4) membranes were synthesized via a facile liquid based preparation method by using SiO2 membranes as substrates. Perylene imide distributes uniformly in PI-g-C3N4, enhancing the separation of photo generated electron-holes. The membrane form of PI-g-C3N4 is favored to its applications due to the easy operation and separation process. The PI-g-C3N4 membranes exhibit efficient photocatalytic degradation of organic pollutants in the presence of PMS under visible light irradiation, which could remove 100% BPA within 30 min. ESR analysis and radical quenching experiments indicate that O-1(2), O-2(center dot)- radicals and h(+) are predominant active species in the degradation process. This study presents a facile strategy for PI-g-C3N4 membrane preparation, and brings new perspectives for the application of metal free membrane catalysts in the area of water treatment. |
