In situ synthesis process of nanographene and its characteristic

Abstract

The results of the study of synthesis nano graphene from pyrolysis of tartaric acid compound obtained 29.8% yield. Crystallinity of nano graphene was analyzed by X-ray diffractometer and showed peak 2θ at 23.15° from the diffractogram. Nano graphene from tartaric acid has a particle size of 1 nm by the result of atomic force microscopy analysis. The photoluminescent properties were measured using spectrofluorometer with a 405 nm Diode Laser producing a peak at wavelength of 403.1 nm (blue region). Nano graphene maintain its stability in the pH range of 3-12 as well as on the addition of salt with concentration of 0.15 M; 0.30 M; and 0.50 M for 24 hours.
