Novel Nanostructures of Porous Carbon Synthesized with Zeolite LTA-Template and Methanol

Novel nanostructured carbon material was synthesized by applying zeolite LTA as a template and using methanol as a carbon source. X-ray diffraction (XRD) revealed that the higher the decomposition temperature, the more graphitic and ordered the structure. The optimum pyrolytic temperature for addition of microporosity was below 1273 K by analysis of N 2 adsorption isotherm. The resultant carbons have the long-range periodic structure of a nanoscale curvature according to XRD and Raman spectroscopic examinations. The morphological similarity between zeolite LTA and synthesized carbon was evidenced by scanning electron microscopic observation. Grand canonical Monte Carlo simulation of N 2 adsorption isotherm indicates that synthesized nanoporous carbon has a hollow hemispherical structure of which diameter is less than 0.7 nm.
