Abstract
Aerogel-type silica has been synthesized via precipitation of a hydrogel from liquid glass in the presence of glycerol followed by an extraction treatment with ethanol. Isotherms of low-temperature nitrogen adsorption-desorption by the prepared samples have been measured. It has been shown that the mesopore size distribution becomes more uniform with an increase in the pH of precipitation and the amount of glycerol, as well as after the extraction treatment of both a liquid hydrogel and xerogels dried at 293 and 373 K.
