Spectral and structural properties of luminescent carbon
nanoparticles obtained by electrolysis of an alcohol solution of NaOH
Abstract
Abstract.Carbon nanoparticles were obtained as a result
of electrolysis of sodium hydroxide solution in 94% ethanol on platinum
electrodes. Centrifugation, column chromatography, and dialysis were used to
isolate and purify nanoparticles from synthesis by-products. The nanoparticles
had a hydrodynamic diameter of about 14 nm, and the surface potential was –20
mV. The particles are soluble in water due to hydroxyl and carboxyl groups on
the surface, and also 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.
Key words: carbon nanoparticles, electrochemical
synthesis, luminescence
