摘要：Nanosized mesoporous AlKIT-1 molecular sieve was hydrothermally synthesized in the absence of organic salts. The samples were characterized by X-ray diffraction, electron microscopy (TEM and SEM), N(2) adsorption isotherm, and NH(3)-TPD methods. The AlKIT-1 has a particle size of about 60-100 nm, and a three-dimensional network structure with average pore size of 2.7 nm. The sample exhibits good hydrothermal stability and catalytic performance for 1,2,4-trimethylbenzene, suggesting its promising applications in the conversion of large molecules.
