posted on 2019-12-13, 13:12 authored by Wei Cai, Jiayu Tang, Yunpeng Shi, Hu Wang, Xiaoming JiangA simple, in situ, and one-pot hydrothermal strategy
was applied for the successful manufacturing of heterostructured 2D/2D
BiOCl/g-C3N4 photocatalysts, and outstanding
photodegradation of Rhodamine B in the condition of visible-light
irradiation over the composites emerged. The investigation of various
BiOCl/g-C3N4 ratios influencing the activity
implied that the optimized B2C1 (mole ratio of BiOCl/g-C3N4 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-C3N4, 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-C3N4 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.
