A New Graphitic Carbon Nitride/Horseradish Peroxidase Hybrid Nano-Bio Artificial Catalytic System for Unselective Degradation of Persistent Phenolic Pollutants

It has always been a challenge to fabricate artificial catalytic system as one promising strategy of using solar energy for chemical synthesis, fuel production, electrochemical detection, pollutant degradation, etc. Here a new g-C3N4/horseradish peroxidase hybrid nano-bio artificial catalytic system is exploited. The coupling effect between photocatalysis and biocatalysis cycles not only forcefully improves the separation efficiency of charge carriers but also continuously produces more OH active species, finally realizing high-efficiency and unselective degradation of various persistent phenolic pollutants, such as bisphenol A, phenol, p-nitrophenol, and 2-naphthol. This work provides an innovative design idea to fabricate general artificial catalytic system that may be widely used in treatment of organic pollutants.
