Abstract:

Mesoporous inorganic alumina with framework walls has been synthesized using a new and simple non-supercritical drying method. As a substitute solvent, hexamethyl disilylamine (HMDS) plays a definitive part for synthesis of the mesoporous alumina due to its special characters. The resulting alumina product shows high BET surface area, concentrated distribution of diameter and high porosity. The pore size distribution of alumina we prepared is concentrated around 11nm. Its structure still maintained stable and the BET surface area could reach up to 413.4593m²/g after being calcined at 800°C.
