- Abstract
Small-mesopore-added silicalite-1 zeolites were prepared by using single wall carbon nanohorn (SWCNH) as a template. The samples were characterized with X-ray powder diffraction, field emission scanning electron microscopy, transmission electron microscopy (TEM) and molecular probe adsorption methods. The pore size distributions determined with N adsorption at 77 K showed the presence of small mesopores in 2-4 nm pore widths, in addition to their intrinsic micropores of 0.58 nm. The mesopore volume was 0.06 cm g. The presence of small mesopores in the SWCNH-templated silicalite-1 zeolites was supported with TEM observation as well as the liquid phase adsorption of methylene blue, which was much higher than that on a bulk (purely microporous) silicalite-1.
