摘要：A composition of matter is provided including an inorganic porous material having wall portions defining mesopore-sized channels having a mean diameter of between about 15 ANGSTROM and about 100 ANGSTROM and a narrow diameter distribution of less than or equal to about 30 ANGSTROM , the material having a void volume from the mesopore-sized channels of at least about 0.1 cc/g and a surface area of at least about 500 m2/g and having a number of hydroxyl groups of at least about 1.5 mmol of hydroxyl groups per gram of material, and exhibiting thermal and hydrothermal stability at temperatures up to about 500 DEG C. Catalytic materials incorporating aluminum and other active metals, as well as a process for preparing the composition, are also disclosed.
