To tackle the concern of hexavalent chromium (Cr(VI)) contamination, a photocatalytic adsorbent, chitosan/ carbon dots modified cellulose nanofibrils/ZIF-8 gel bead (CCCZ), was synthesized as an effective and easily separable material for Cr(VI) removal. A comprehensive analysis of CCCZ encompassing diverse analytical techniques was conducted to explore its morphology, structure, optical properties, as well as its adsorption and photocatalytic behaviors. Adsorption experiments revealed the exceptional adsorption capacity of CCCZ for Cr (VI), with a maximum capacity of 500.08 mg/g, surpassing t...
