This thesis discusses the colloid-chemical properties of carbon dots (CDs) in aqueous media. Carbon dots are carbon-based nanoparticles that can form stable aqueous dispersions depending on particle size, surface functional groups, pH, ionic strength, and medium composition. Surface groups such as –OH, –COOH and C=O contribute to hydrophilicity, surface charge and colloidal stability. The role of zeta potential, electrostatic repulsion, aggregation and sedimentation is considered. Understanding these parameters is important for controlling aqueous Carbon dot dispersions obtained from natural coal and for evaluating their potential practical applications.
