Seeded growth strategy to synthesize NH 2 ‐MIL‐88B(Fe) embedded on reduced graphene oxide (NM88@RGO) is reported in this work. The 2D NM88@RGO composites show intensive Fenton‐like catalytic performance in the visible light‐driven degradation of contaminant. Among as‐synthesized samples, NM88@RGO‐15 is confirmed to possess the highest catalytic activity to the removal of RhB within 1 h and the efficiency is held at high level after 5 cycles. Besides, the synergistic interaction between NH 2 ‐MIL‐88B(Fe) and RGO and photocatalytic mechanism are investigated thoroughly by the electrochemical measurements, the trap experiment of active species, and the analysis of energy‐level position. RGO is capable of acting as a template to direct the formation of 2D nanostructures and behaves as an electron‐captured net to facilitate the charge transfer and inhibit the recombination of electron‐holes on the NH 2 ‐MIL‐88B(Fe). The homogeneous distribution of Fe‐MOFs particles on RGO nanosheets is in favor of the formation and exposure of active sites for light‐driven Fenton‐like reaction.
