Aluminum-containing MCM-41 mesoporous materials were synthesized at the conditions of 10 and 9 of the gel pH by utilizing a method of adjusting the equilibrium in the gel using acetic acid. The structure of MCM-41 was characterized by XRD, N₂adsorption and TME; the hexagonal array structure of meso pores was identified. The solid acidity was characterized by IR of adsorbed pyridine, TPD of ammonia and test reactions such as the isomerization of 1-butene and the cracking of cumene. The catalytic activities of AI-MCM-41 with a SiO₂/AI₂O₃ratio of 17 were similar to those of typical silica-alumina catalyst.
