Abstract
We obtain carbon nanoparticles by the electrolysis of sodium hydroxide solution in 94% ethanol on platinum electrodes. Centrifugation, column chromatography, and dialysis are used to isolate and purify nanoparticles from synthesis by-products. The nanoparticles have a hydrodynamic diameter of approximately 14 nm, and their surface potential is –20 mV. The particles are soluble in water due to the hydroxyl and carboxyl groups on their surface and exhibit luminescence in the blue and orange regions of the visible spectrum. The paper discusses the details of the electrochemical synthesis of nanoparticles of this type.
