Abstract

The g-C3N4/BiOCl microsphere photocatalysts have been successfully synthesized in the presence of the reactable ionic liquid [C16mim]Cl. The p-n junction between p-type BiOCl and n-type g-C3N4 has been successfully constructed with g-C3N4 dispersed on the surface of BiOCl microspheres. The g-C3N4/BiOCl microspheres were characterized by XRD, XPS, SEM, FT-IR, and DRS. Rhodamine B (RhB) was used as a target pollutant to evaluate the photocatalytic activity of the as-prepared g-C3N4/BiOCl microsphere photocatalysts. The g-C3N4/BiOCl material exhibited superior photocatalytic performance when compared with pure BiOCl. The formed p-n junction was responsible for the improved separation efficiency of photogenerated electron–hole pairs, and thus the higher photocatalytic activity. The possible photocatalytic mechanism was proposed based on relative band positions of these two semiconductors.
