Rational design 2D/2D BiOBr/CDs/g-C3N4 Z-scheme heterojunction photocatalyst with carbon dots as solid-state electron mediators for enhanced visible and NIR photocatalytic activity: Kinetics, intermediates, and mechanism insight
Abstract
Abstract Rapid recombination of photogenerated carriers and narrow visible light absorption range are two main defects in graphitic carbon nitride (g-C3N4)-based photocatalysts. To address these problems, construction of Z-scheme 2D/2D BiOBr/CDs/g-C3N4 heterojunction photocatalysts with carbon dots as solid-state electron mediators has been investigated. The resultant BiOBr/CDs/g-C3N4 hybrids exhibits remarkable interfacial charge transfer abilities and a broadened solar light absorption range owing to the short charge transport distance and the up-converted photoluminescence character of CDs. Simultaneously, the enhanced specific surface area and nanosheet structure impart more active sites to BiOBr/CDs/g-C3N4 composites. As a result, BiOBr/CDs/g-C3N4 composites reveal significant enhancement in the activity of photodegradation of ciprofloxacin (CIP) and tetracycline (TC) under visible and near infrared (NIR) light irradiation. Moreover, the photodegradation efficiency of BiOBr/CDs/g-C3N4 hybrids was significantly enhanced over that of pristine BiOBr nanosheets and g-C3N4 ultrathin nanosheets. The photocatalytic mechanism is expounded according to free radical capture experiments and electron spin resonance spin-trapping tests and the photodegradation intermediates of CIP were detected by liquid chromatography–mass/mass spectrometry. Moreover, BiOBr/CDs/g-C3N4 composites show excellent photostability and reusability after four runs for CIP degradation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
