Novel carbon quantum dots/zinc aluminum layered double hydroxide (CQD/ZnAl-LDH) composite was prepared through the precipitation of metal nitrates in the presence of CQD by a facile and simple method and further applied to remove excessive Cd(II) ions from water. The chemical composition and morphology of the CQDs/ZnAl-LDH hybrid was investigated by Fourier transform infrared spectroscopy, X-ray diffraction,...
In this paper, highly amino-functionalized fluorescent carbon quantum dots (CDs) were fabricated by hydrothermal carbonization of chitosan at mild temperature. Multiwall carbon nanotubes (MWCNTs) and CD were used in the preparation of working electrode. This sensor was based on a poly (diallyl-dimethyl ammonium chloride)/MWCNT/CD modified pencil graphite electrode for monitoring dextromethorphan (DXM)...
