Abstract:Carbon quantum dot (CQD) decorated semiconductor materials have become promising photocatalysts in photocatalysis, with a chance to solve energy and environmental crises. Red emissive carbon quantum dots (R-CQDs) have excellent photoluminescence (PL), upconversion, narrowed band structure, electron-accepting, and transmission properties compared to other colors emitting CQDs. In this work, we use the as-synthesized R-CQDs to decorate P25 (R-CQDs/P25) for highly enhanced visible-light photocatalysis. The result… Show more
“…Electrochemical impedance spectroscopy (EIS) is also a commonly used method for photoelectrochemical testing, where the arc radius can reflect the charge transfer rate, and a smaller radius indicates a higher charge transfer efficiency. 42 From Fig. 6c, it can be note that the impedance radius of the composite material is much smaller than that of pure BiVO 4 .…”
Designing efficient, inexpensive, and stable photocatalysts to degrade organic pollutants and antibiotics has become an effective way for environmental remediation. In this work, we successfully in-situ grow CdS QDs on...
