Abstract

Herein, a method is described for pyrolysis associated with in situ ultrasonic synthesis of flower-like p-n-type BiOCl/g-C3N4 assembled with nanosheets for enhancing the visible-light degradation of Rhodamine B (RhB). The formation process, structure, microscopic morphology, and photocatalytic activity of the samples were investigated in detail. In addition, the results of simulated visible light-driven photocatalytic experiments showed that, compared with pure g-C3N4, the BiOCl (20 wt %)/g-C3N4 composite photocatalyst exhibited better degradation ability with a maximum k value of 0.109 min−1, and the most significant total removal rate of RhB was up to 99 %, which is about ninefold in comparison with pure g-C3N4. Finally, the enhanced photocatalytic activities of the products could be attributed to the suitable band structures between the BiOCl/g-C3N4 composite with rich oxygen vacancies for the effective separation of photogenerated electron–hole pairs.
