Photochemical vapor generation (PCVG) is a green and effective sampling technology for analytical atomic spectrometry, and in recent years it has been received continuous attention. In this work, visible light photochemical vapor generation was achieved with metal-free g-C3N4/CQDs (carbon nitride/carbon quantum dots) composites as a photocatalyst, and used for selective and ultrasensitive detection...
In this work, we proposed a dielectric barrier discharge (DBD)-assisted one-pot strategy to fabricate carbon quantum dots (CQDs) using only one reagent N, N-dimethylformamide (DMF) at atmospheric pressure and room temperature. The experimental conditions were carefully investigated, and the prepared CQDs were characterized by using UV–vis spectrophotometer, fluorescence spectrophotometer, Fourier...
