Texture control and characterization of mesoporous aluminamaterial bulk prepared by hydrothermal hot-pressing method

Abstract

Dense mesoporous alumina bulks were successfully synthesized by a hydrothermal hot-pressing (HHP) method. First, mesoporous alumina was prepared as starting material which possesses a high BET surface area and narrow pore size distribution. Mesoporous alumina bulks prepared by hydrothermal hot-pressing (HHP) had high density with uniformity pore size distribution and a high specific surface area. Their features for dense mesoporous alumina bulks were observed by SEM and mesopores were evaluated by XRD, N2 adsorption/desorption technique, TEM and humidity conditioning property.
