Abstract

A method of fabricating an ultraporous SiO2 containing gel monoliths having a predetermined mean pore size with narrow distribution of the size of the pores around the mean. A SiO2 containing sol is prepared while simultaneously controlling and preselecting the temperature, time and nature of aging solution, and drying the resultant gel to obtain an ultraporous SiO2 containing monolith having a predetermined mean pore size from about 10 Å to about 400 Å with narrow distribution of the size of pores around the mean and the resultant article.
