Fluorescent chitosan-based hydrogel incorporating titanate and cellulose nanofibers modified with carbon dots for adsorption and detection of Cr(VI)

Qiuyan Luo et al.

Summary: A novel fluorescent chitosan-based hydrogel incorporating titanate and cellulose nanofibers modified with carbon dots was prepared to effectively detect and remove Cr(VI). The hydrogel showed a high adsorption capacity for Cr(VI) along with good sensing abilities, enabling quantitative detection within a linear range. Analysis revealed that the excellent sorption and sensing capabilities were mainly attributed to the porous structures and the modification of carbon dots.

Carbon nitride-doped melamine-silver adsorbents with peroxidase-like catalysis and visible-light photocatalysis: Colorimetric detection and detoxification removal of total mercury

Mengyuan Yin et al.

Summary: Mesoporous melamine-silver nanocomposites doped with carbon nitride quantum dots were fabricated through controlled supramolecular self-assembly. The resulting nanoflower-like nanocomposites exhibited peroxidase-like catalysis, which could be enhanced by Hg2+ and effectively detoxify Hg-0 in wastewater through visible-light-driven photocatalysis. These nanocomposites also showed high Hg adsorption capability and promise for environmental monitoring and wastewater treatment of toxic heavy metals.
