To investigate the influence of graphene on the photocatalytic activity of bismuth ferrite (BiFeO 3 ), BiFeO 3 and flaky BiFeO 3 @graphene were prepared through the hydrothermal‐synthesis process. The as‐prepared particles were characterised by XRD, TGA, SEM, X‐ray photoelectron spectroscopy, and PL measurements. The results show that the BiFeO 3 nanoparticles have a microstructure and homogeneously attached to graphene sheets. Moreover, the flaky BiFeO 3 @graphene composites exhibited higher photocatalytic efficiency than pure BiFeO 3 , especially under visible light irradiation. The synergistic effects of graphene and BiFeO 3 of composites were proposed to guide the further improvement of their photocatalytic activity.
