Near-infrared light controlled photocatalytic activity of carbon quantum dots for highly selective oxidation reaction.
Selective oxidation of alcohols is a fundamental and significant transformation for the large-scale production of fine chemicals, UV and visible light driven photocatalytic systems for alcohol oxidation have been developed, however, the long wavelength near infrared (NIR) and infrared (IR) light have not yet fully utilized by the present photocatalytic systems. Herein, we reported carbon quantu...
متن کاملFe2O3/carbon quantum dots complex photocatalysts and their enhanced photocatalytic activity under visible light.
In this study, we report the facile fabrication of Fe(2)O(3)/CQDs nanocomposites, and investigate their effective photocatalytic activity for the photodegradation of toxic gas (gas-phase benzene and methanol) under visible light. The crucial roles of CQDs in the enhancement of photocatalytic activity of the Fe(2)O(3)/CQDs composites are illustrated.
متن کاملThe synergistic role of carbon quantum dots for the improved photocatalytic performance of Bi2MoO6.
Novel carbon quantum dot (CQD) modified Bi2MoO6 photocatalysts were prepared via a facile hydrothermal process. The CQD modified Bi2MoO6 materials were characterized by multiple techniques. The CQDs with the average size of about 7 nm were distributed on the surface of Bi2MoO6 nanosheets. The photocatalytic activity of as-prepared CQD modified Bi2MoO6 materials was investigated sufficiently by ...
متن کاملCarbon quantum dots enhance the photocatalytic performance of BiVO4 with different exposed facets.
Carbon quantum dots (CQDs) were demonstrated to have the ability to enhance the photocatalytic performance of monoclinic BiVO4 with different exposed facets under visible light.
متن کاملPhotocatalytic carbon disulfide production via charge transfer quenching of quantum dots.
Carbon disulfide, a potentially therapeutic small molecule, is generated via oxidative cleavage of 1,1-dithiooxalate (DTO) photosensitized by CdSe quantum dots (QDs). Irradiation of DTO-QD conjugates leads to λ(irr) independent photooxidation with a quantum yield of ~4% in aerated pH 9 buffer solution that drops sharply in deaerated solution. Excess DTO is similarly decomposed, indicating labil...
