CO₂ Adsorption by Carbon Quantum Dots/Metal Ferrites (M = Co²⁺, Ni²⁺, and Zn²⁺): Electrochemical and Theoretical Studies.

ABSTRACT: In this study, we investigated the adsorption of CO₂ by carbon quantum dot-based ferrites (MFe₂O₄, M = Co²⁺, Ni²⁺, and Zn²⁺) in the context of industrial CO₂ emissions and global warming. The ferrites have been characterized using various analytical techniques [X-ray powder diffraction, FTIR, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS)], showing cubic spinel for CoFe₂O₄, reverse cubic spinel for NiFe₂O₄, and typical spinel for ZnFe₂O₄. A TGA study revealed a significant weight loss around 740-780 °C, indicating structural change occurred with
