主 题：Dual reaction centers Fenton Pollutant utilization Electron transfer
摘 要：Triggered by global water quality safety issues,the research on wastewater treatment and water purification technology has been greatly developed in recent years.The Fenton technology is particularly powerful due to the rapid attack on pollutants by the generated hydroxyl radicals(·OH).However,both heterogeneous and homogeneous Fenton/Fenton-like technologies follow the classical reaction mechanism,which depends on the oxidation and reduction of the transition metal ions at single sites.So even after a century of development,this reaction still suffers from its inherent bottlenecks in practical application.In recent years,our group has been focusing on studying a novel heterogeneous Fenton catalytic process,and we developed the dual-reaction-center(DRC)system for the first time.In the DRC system,H2O2 and O2 can be efficiently reduced to reactive oxygen species(ROS)in electron-rich centers,while pollutants are captured and oxidized by the electron-deficient centers.The obtained electrons from pollutants are diverted to the electron-rich centers through bonding bridges.This process breaks through the classic Fenton mechanism,and improves the performance and efficiency of pollutant removal in a wide pH range.Here,we provide a brief overview of Fenton s story and focus on combing the discovery and development of the DRC technology and mechanism in recent years.The construction of the DRC and its performance in the pollutant degradation and interfacial reaction process are described in detail.We look forward to bringing a new perspective to continue Fenton s story through research and development of DRC technology.
