Abstract

A new strategy for constructing visible-light-driven catalysts is to create NH₂-MIL-88B (Fe) / PDA / rGO composites by polydopamine bridge crosslinked graphene oxide and NH2-MIL-88B (Fe). In this paper, the charge transfer mechanism is proposed. This mechanism is involved in the photoinduced electron transfer to the electron trap of graphene oxide through PDA channels and holes captured by it so that the electron-hole pair is effectively separated and the charge recombination is inhibited, prolonging the lifetime of the photogenerated carriers. At the same time, this work also exposed more active phases of NH₂-MIL-88B (Fe) in go and PDA to promote the application of polydopamine bridging materials in photocatalysts with high energy visible light activity.
