Photocatalytic activation of peroxymonosulfate by carbon quantum dots functionalized carbon nitride for efficient degradation of bisphenol A under visible-light irradiation

Advanced oxidation process (AOP) through the photocatalytic activation of peroxymonosulfate (PMS) has attracted much attention in wastewater treatment. Herein, a metal-free carbon quantum dots (CQDs) functioned polymer carbon nitride (PCN) was synthesized and used as an efficient photocatalyst for PMS activation toward bisphenol A (BPA) degradation under visible-light irradiation. The incorporation of CQDs in PCN endowed it with enlarged surface...
