Zeolite Y of mesoporous channels has been synthesized using novel mesoporous carbon aerogels as template. It was characterized with X-ray powder diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy (FE-SEM), thermogravimetric analysis, and nitrogen adsorption/desorption. The pore size distribution with N-2 adsorption shows the presence of mesopores and micropores whose average pore widths are ca. 10 and 0.75 nm, and pore volumes are 1.37 and 0.21 cm(3) g(-1), respectively. FE-SEM observation supports the presence of mesopores.
