Bi2O3/Bi2SiO5 heterojunction was in-situ constructed on exfoliated montmorillonite via an one-pot method. The crystal structure, morphology, and optical features for the as-synthesized Bi2O3/Bi2SiO5 heterojunction were characterized. In the preparation process, the exfoliated montmorillonite acts as Si source and framework for the in-situ formation of Bi2O3/Bi2SiO5 p-n heterogeneous junction on montmorillonite interlayer. As a result, Bi2O3/Bi2SiO5 photocatalyst exhibits a superior photocatalytic performance rather than bare α-Bi2O3 for the degradation of Rhodamine B (RhB) via the simulated solar light irradiation due to the synergetic effects of large specific surface areas and p-n junction between Bi2SiO5 and Bi2O3. Moreover, a possible photocatalytic mechanism for the as-prepared photocatalysts was proposed. This work provides a new insight into synthesizing the cost-efficient photocatalyst with montmorillonite for the contaminant degradation.
