What is of SILICA with CAS 10279-57-9?
S.A.250m^2/gSilicon oxide is used as a catalyst support material having a high surface area. It acts as a medium to which catalyst is affixed. Several metals such as platinum, rhodium, ruthenium, silver, copper, nickel, iron, manganese, cobalt, tungsten and gold are supported over silicon dioxide and used as a catalyst in synthetic chemistry for various applications. For example, silica-supported gold catalysts is used for carbon monoxide oxidation by a solution-based technique.
