Stable synthetic material and method for preparing same

A process for preparation of an inorganic porous material, comprising the steps of:

• forming a solution of a hydrolyzable inorganic compound with tensoactive organic molecules comprising a non-ionic surfactant;
• inducing growth and condensation of a solid composition comprising an inorganic composition in intimate contact with said organic molecules by adjusting the solution to a pH equal to or within about ±2 pH numbers of an isoelectric point mean value of inorganic species of the inorganic compound;
• and
• extracting said organic molecules with a solvent so as to provide an inorganic porous solid composition having 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° C.
