Sugarcane waste-derived carbon quantum dots-chlorophyll/bacterial cellulose composites for solar-driven antibiotic degradation.

ABSTRACT: A bio-based CQDs-Chl/BC nanocomposite (NCs) was synthesized from sugarcane bagasse, sugarcane leaves, and bacterial cellulose (BC) via a green bio-construction strategy to enhance antibiotic removal through a synergistic adsorption-photocatalysis mechanism. CQDs were prepared by a microwave-assisted method, Chl was extracted from sugarcane leaves, and BC provided a renewable support matrix. The incorporation of CQDs and Chl broadened visible-light absorption and improved charge transfer, as confirmed by UV-Vis spectroscopy, FTIR, PL, TEM-EDS, and XPS analyses. Förster resonance energy transfer (FRET) and photoinduced electron transfer (PET) minimized charge recombination, while LC-MS spectra of degradation products identified transient intermediates of ciprofloxacin (CIP) and oxytetracycli
