Improved in Situ Synthesis of Heterostructured 2D/2D BiOCl/g-C(3)N(4) with Enhanced Dye Photodegradation under Visible-Light Illumination

[Image: see text] A simple, in situ, and one-pot hydrothermal strategy was applied for the successful manufacturing of heterostructured 2D/2D BiOCl/g-C(3)N(4) photocatalysts, and outstanding photodegradation of Rhodamine B in the condition of visible-light irradiation over the composites emerged. The investigation of various BiOCl/g-C(3)N(4) ratios influencing the activity implied that the optimized B2C1 (mole ratio of BiOCl/g-C(3)N(4) with 2:1) exhibited the higher degradation efficiency than that of the rest of the composites, even higher than that of pure BiOCl and pure g-C(3)N(4), which yielded over 90% in the initial 30 min and reached almost 100% during the whole 70 min irradiation process. Kinds of characterizations demonstrated that the enhancement of photodegradation performance was caused by the intimate contact between BiOCl and g-C(3)N(4) to form the heterostructure, which could benefit the generation of abundant visible-light photoinduced carriers and help enhance their separation and then promote their transportation to the surface.
