<p>Disclosed herein are mesoporous material derived from a parent zeolite. In an embodiement of the invention, the mesoporous material derived from a parent zeolite, has an internal volume greater than about 0.35 cc/g and a surface area greater than about 250 m<SUP>2</SUP>/g, the mesoporous material comprises micropores having a surface area and mesopores, wherein the surface area of the micropores in the mesoporous material is less than about 25% of that in the parent zeolite, wherein less than about 3% of the internal volume of the mesoporous material is provided by micropores and wherein the mesopores are essentially homogeneously distributed and form an essentially interconnected network. In another embodiment of the invention, the mesoporous material derived from an alumina-rich parent zeolite has an internal volume greater than about 0.25 cc/g and a surface area greater than about 95 m<SUP>2</SUP>/g, the mesoporous material comprises micropores having a surface area and mesopores, wherein the surface area of the micropores in the mesoporous material is less than about 25% of that in the parent zeolite, wherein the mesopores are essentially homogeneously distributed and form an essentially interconnected network and wherein the mesoporous material further comprises at least one element selected for the group consisting of cerium, lanthanum and yttrium. Also disclosed are methods of manufacture and uses for the same.</p> |
