Sorption of vapors of Cd at 480–600 °C and of Zn at 750–880 °C by SBA-15 was studied. The amounts of deposited metal ranged from 1 to 11% of the mass of silica, and they were especially high with long deposition times (up to 3 days) at relatively low temperatures. The specific surface areas after metal deposition were lower than those of the original SBA-15 silica, and they decreased with metal contents. The products of deposition of metals on silica can be considered as new materials, metal-modified silicas.
