Abstract
Turbostratic mesoporous carbons were synthesized by catalytic decomposition of acetylene over Cu/MgO or Cu/Al2O3 catalysts. The carbon samples were characterized by X-ray diffraction (XRD), nitrogen adsorption, transmission electron microscopy (TEM) and thermo gravimetric analyser (TGA). The decomposition of temperature was found having crucial effect on the microstructure and reactivity of carbon samples. Increase of decomposition temperature leads to the decrease of the surface area and growth of carbon crystatlite volume (V-nano), which make the chemical reactivity of carbons reduced. It was found that V-nano is a useful parameter to describe the effect of the crystalline structure on the reactivity of turbostratic carbons in oxygen-carbon reaction.
