Synthesis and Surface Engineering of Carbon Quantum Dots by Electrical Discharges Generated Inside and in Contact with Liquid

In this paper electrical discharge plasma in liquid was used for synthesis of carbon nanoparticles (NPs). In addition, targeted changes of the NPs surface properties were selectively achieved via treatment of as-prepared NPs by a gas-liquid interfacial discharge produced in contact with the colloidal solution. The results of the solution chemistry induced at the plasma-liquid interface for surface engineering of NPs are discussed.
