Abstract

Water sorption on the surfaces of pyrogenic SiO2 (S=290 m2/g) and TiO2 (S=50 m2/g) has been studied. The dielectric isotherm curves show that on the surface of TiO2 (anatase) a continuous water layer is formed at Θ=1.9 but none is formed on the silica surface. Sorption occurs only as definite clusters.
