摘要: Abstract Developing new energy resource as well efficient treatment strategies to solve the crisis and organic pollutants problems is of crucial importance. Due medium band gap highly thermal stability, doped or chemically functionallized graphitic carbon nitride (g-C3N4) has been envisioned promising photocatalysts in processing pollutants. In this work, we use 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) modified g-C3N4 degrade Rhodamine B (RhB) under visible light irradiation (λ ≥ 420 nm). When weight ratio BODIPY reaches 0.6% (CN-0.6), photocatalytic performance nearly 3.5 times fast than that without modification (CN-0). Enhanced absorption depressed electron-hole recombination rate may take responsibilities for enhanced photocalytic performance. A possible mechanism responsible process proposed. Our work might provide a strategy develop valid with broad absorption.
