Enhanced photocatalytic activity of Bi₁₂O₁₇Cl₂ preferentially oriented growth along [200] with various surfactants

In this study, Bi₁₂O₁₇Cl₂ nanosheets preferentially oriented growth along [200] were successfully synthesized through a facile hydrothermal method in the presence of various surfactants, including PVP, CTAB and CTAC. The crystallization behavior, band gap structure and morphology of Bi₁₂O₁₇Cl₂ could be modulated by the addition of surfactants. Bi₁₂O₁₇Cl₂ with surfactants displays superior visible light photocatalytic performance than pristine sample for photodegrading RhB and 2-chlorophenol. Moreover, Bi₁₂O₁₇Cl₂ preferentially oriented growth along [200] maintained stable and recyclable in the photocatalytic process, demonstrating their promising application in environment remediation.
