Description
Summary:Novel two-dimensional graphitic carbon nitride (g-C 3 N 4 )/BiOCl nanosheets with excellent photodegradation activity towards rhodamine B (RhB) under visible light irradiation have been successfully synthesized by a sonication-assisted deposition–precipitation route. The composite nanosheets exhibited good dispersity and abundant contact interfaces, which led to the formation of p–n heterojunctions. Hybridization of g-C 3 N 4 in the composites resulted in an extended absorption range and inhibited the recombination of the photoinduced charge carriers. Therefore, the two-dimensional heterostructure of the present compounds contributed to enhance their photocatalytic performances. In addition, the indirect photosensitization effect of RhB also influenced the photodegradation activity of BiOCl.
