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 &angst; and about 100 &angst; and a narrow diameter distribution of less than or equal to about 30 &angst;, 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 m /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.
