Research Abstract

n this study, the synthesis of bulky zeolite materials was attempted by a hydrothermal hot-pressing(HHP)method at relatively low temperatures, in which the conventional hydrothermal processings were modified. The obtained zeolite bulks had dense microstructures without large voids and extremely high values of specific surface areas of over 200 m^2/g. TEM and SEM observations showed that the zeolite bulks synthesized by this a hydrothermal hot-pressing(HHP)method possessed uniform pores and no amorphous phase at the interface between grains, leading to these bulky zeolite bodies with interconnected pore-networks. As a result, dense bulky bodies with micoropores and high values of specific surface areas could be obtained by this a hydrothermal hot-pressing (HHP) method. These bulky and dense zeolite bodies are expected to be applicable as catalysts, adsorbents, and sensors.
