Carbon nitride exfoliation for photocatalysis and photocatalytic ozonation over emerging contaminants abatement
Abstrakt
The production of graphitic carbon nitride was studied with the addition of a following exfoliation step using ultrasounds, at different times. The treatment produced catalysts with much higher surface areas, from 2.18 m2 g 1 with no treatment to 28.34 m2 g 1 after 36 h of exfoliation. During exfoliation, melem was also produced, and may further enhance the photoluminescence and photocatalytic properties. The photocatalytic reaction also indicated the improved performance of exfoliated g-C3N4 towards the degradation of a mixture of parabens, enhancing their removal from 20% to up to 65% in 2 h under UVA radiation. The combination of ozone and g- C3N4 photocatalysis was able to completely remove the parabens in under 8 min and with a 20% lower consumption of ozone compared to photolytic ozonation. The main reactive species were identified, and the byproducts formed during parabens degradation were detected. The efficiency of the combined system was also attested by using a mixture of parabens and other common drugs, maintaining its better performance.
