摘要
Monolithic catalyst support structures in which a support phase of high surface area oxide material is disposed on or within a sintered ceramic material are improved by using a mixture of alumina and silica as the high surface area oxide support phase. The mixtures of alumina and silica retain higher surface area, after firing or exposure to elevated service temperatures, than does either component individually, and thereby impart higher overall surface area to the monolithic support structures.
