| description | In the present work, a facile one-step methodology was used to synthesize honeycomb-like BiFeO<sub>3</sub>/g-C<sub>3</sub>N<sub>4</sub> composites, where the well-dispersed BiFeO<sub>3</sub> strongly interacted with the hg-C<sub>3</sub>N<sub>4</sub>. The 10BiFeO<sub>3</sub>/hg-C<sub>3</sub>N<sub>4</sub> could completely degrade RhB under visible light illumination within 60 min. The degradation rate constant was remarkably improved and approximately three times and seven times that of pristine hg-C<sub>3</sub>N<sub>4</sub> and BiFeO<sub>3</sub>, respectively. This is ascribed to the following factors: (1) the unique honeycomb-like morphology facilitates the diffusion of the reactants and effectively improves the utilization of light energy by multiple reflections of light; (2) the charged dye molecules can be tightly bound to the spontaneous polarized BiFeO<sub>3</sub> surface to form the Stern layer; (3) the Z-scheme heterojunction and the ferroelectric synergistically promoted the efficient separation and migration of the photogenerated charges. This method can synchronously tune the micro-nano structure, surface property, and internal field construction for g-C<sub>3</sub>N<sub>4</sub>-based photocatalysts, exhibiting outstanding potential in environmental purification. |
