A novel aluminosilicate with bimodal mesopore distribution -synthesis and characterization

摘要

A novel aluminosilicate material (denoted as NKF-2) with well- defined bimodal mesopore distribution has been hydrothermally synthesized directly using cetyltrimethylammonium chloride and tetraethylammonium hydroxide as mixed templates, in which one mesopore is distributed at around 3.8 nm and the other at 2.6 nm. The synthesized samples were characterized by powder X-ray diffraction (XRD), scanning electron microscopy, N_2 adsorption, infrared spectroscopy, thermo-gravimetic analysis and solid-state ~27Al and ~29Si magic-angle-spinning (MAS) NMR spectroscopies to understand both the pore structures and the local atomic arrangements of these solid products.
