Coal-based carbon quantum dots modified Ag3PO4/Ni-MOF composites enhanced visible light photocatalytic degradation of phenol

One-Pot Synthesis of C@BiOBr for Efficient Photocatalytic Degradation of Phenol

“…At present, the common schemes used in industry include extraction, adsorption, membrane permeation, etc., but there are some limitations of these methods, like low extraction efficiency, difficult regeneration of adsorbents, and complex processes . At this time, photocatalysis was proposed to degrade pollutants in the wastewater due to its advantages of energy savings, environmental friendliness, and cost-effectiveness, , so large amounts of photocatalysts have been developed, such as TiO 2 , g-C 3 N 4 , and BiOX (X = Cl, Br, I), etc. − In recent years, the photocatalytic degradation of phenolic pollutants has been more focused on the low concentration of pollutant aqueous solutions, and less research has been conducted on the degradation of high-concentration pollutants. , Moreover, phenol is difficult to be mineralized into H 2 O and CO 2 by photocatalytic schemes due to the stable structure of its benzene ring, so the focus of scholars’ research should be on how to oxidize high-concentration phenolic wastewaters and mineralize phenol by photocatalysis. , …”
