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.
