Synthesis of Nanosized AlKIT-1 Mesoporous Molecular Sieve and its Catalytic Performance for the Conversion of 1,2,4-Trimethylbenzene

Abstract

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), N₂ adsorption isotherm, and NH₃-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.

Graphical Abstract

The nanosized AlKIT-1 molecular sieve was synthesized by a simple synthetic route. TEM shows that the pore structure is a three-dimensional, disordered network of short wormlike channels. SEM shows that conglomerate particles have the sphere-like shape and the particle size is about 60–100 nm.
