Carbon spherules: synthesis, properties and mechanistic elucidation

Perfect spherical morphology of non-graphitic carbon is prepared by heating mesitylene at 700 °C in a closed cell. It produced mono-dispersed, 2.5 ± 0.05 μm size carbon spherules with a smooth surface, and which have a surface area of 8 m 2/g. Morphological and structural analysis of the product is...

Description
Summary:Perfect spherical morphology of non-graphitic carbon is prepared by heating mesitylene at 700 °C in a closed cell. It produced mono-dispersed, 2.5 ± 0.05 μm size carbon spherules with a smooth surface, and which have a surface area of 8 m 2/g. Morphological and structural analysis of the product is carried out with TEM, HR-SEM, BET surface area, EDAX, C, H, N, S analysis, XRD, HR-TEM, ESR and Raman spectroscopy. The formation of the spherical shape of the carbon bodies is discussed on the basis of the arrangement of the disordered carbon layers.
