This thesis discusses the preparation of carbon dots from natural coal and the investigation of their colloid-chemical properties in aqueous media. Carbon dots are nanoscale carbon-based materials that may contain hydroxyl, carboxyl, carbonyl and other functional groups on their surfaces. The availability and carbon-rich nature of natural coal make it a promising precursor for carbon dot production. Synthesis conditions and precursor composition can affect particle size, structure, surface chemistry and optical properties. The investigation of dispersion stability, zeta potential, aggregation and pH-dependent behavior is important for understanding the colloidal properties of carbon dots in aqueous systems.
