Construction of g‐C3N4‐Ferrocene Copolymers for Enhanced Visible‐Light Photocatalytic Activity

Abstract To enhance the photocatalytic property of graphitic carbon nitride (g‐C 3 N 4 ), a novel g‐C 3 N 4 ‐Ferrocene copolymers (CNFe) was synthesized via one‐pot thermal polymerization using 1,1‐dibromoferrocene and urea as precursors. Owing to the unique sandwich structure and properties of ferrocene, the specific surface area, visible light absorbance as well as charge carrier separation of CNFe have been simultaneous remarkably enhanced, thus, resulting into a higher photocatalytic activity than pure g‐C 3 N 4 . Benefiting from these structural and compositional features, CNFe exhibited excellent photocatalytic activity for photodegradation of phenol as water pollutants under visible light irradiation with outstanding reusability over five cycles. This current work presents a new insight for constructing polymeric photocatalysts which could be possibly applied in the field of photocatalytic pollution removal for environmental protection.
