Abstract
We have synthesized alumina mesoporous molecular sieves with a cationic surfactant (CTAB) exhibiting thermal stability and high surface area and were also able to synthesize the mesoporous alumina from aluminum alkoxide precursor with cationic surfactant under hydrothermal condition in the presence of formamide as an external additive. The pore sizes and surface area could be controlled by changing of the amount of formamide. The HRTEM image of P-AMS-F showed the disordered interwoven network of the pore architecture. The Al-27 NMR results clearly demonstrate the existence of the different electronic environment around resonant aluminum nuclei
