The template effect of amphiphilic systems on the porous structure of silica gel layers has been studied. Membranes with a tailormade microporosity and pore diameters of between 1 and 2 nm were obtained from these gels. Two different preparation methods have been used and their influence on the sol-
Aqueous sodium silicate solutions and hydrochloric acid were used to prepare silica gels without any additives. In order to establish the optimum conditions for the preparation of microporous and monodisperse gels, the sol-gel reaction has been studied as a function of pH, concentration of silicate,
