英文摘要: Abstract(#br)Bisphenol A (BPA) as a persistent organic pollutant can lead to serious endocrine regulation and carcinogenesis, the high-efficient removal of which is one of the foremost tasks. Here we prepared a photocatalyst/enzyme heterojunction (PEH) via immobilizing horseradish peroxidase (HRP) on mesoporous graphitic carbon nitride (MCN). The fabricated MCN/HRP PEH exhibits the outstanding degradation activity and cycle stability for removing BPA in water. Besides the improved visible light absorption ability and separation efficiency of charge carriers, the outstanding degradation performance of MCN/HRP PEH principally ascribes to the photoenzyme synergic catalytic effect. The reaction mechanism investigation reveals holes, OH and O 2 − all...
