Nano-catalytic behavior of CeO₂ nanoparticles in dye adsorption: Synthesis through bio-combustion and assessment of UV-light-driven photo-adsorption of indigo carmine dye.

ABSTRACT: This study explores the adsorption of indigo carmine dye using bio-combusted cerium oxide nanoparticles (CeO₂ NPs). CeO₂ NPs were synthesized using a bio-combustion method, and then subjected to structural, morphological, and optical characterization for thorough investigation. Structural investigation was carried out using X-ray diffraction (XRD), which revealed a cubic structure with evaluated average crystallite size of 11.55 nm. Later, the same was verified by employing W-H plot (13.57 nm). UV-Vis spectroscopy revealed an effective band gap of 3 eV suited for photocatalytic applications. The metal-oxygen phonon band at 986.32 cm^-1 and 871.96 cm^-1 is confirmed using Infrared Spectroscopy (FTIR). The morphological analysis was done using Transm
