Abstract
A novel zeolite material denoted as ITQ-2-like was synthesized by treating MCM-22 precursor with H2O2 and characterized by various physicochemical techniques (X-ray powder diffraction, transmission electron microscopy, thermogravimetric-differential thermal analyses, Fourier transform infrared spectroscopy and nitrogen adsorption-desorption). It was found that not only the organic template could be completely removed but also the morphology and topology structure of MCM-22 precursor was well preserved after H2O2 treatment. Novel zeolite material ITQ-2-like presented relatively ordered cascaded layers in a face-to-face orientation along the c-axis and exhibited different physicochemical properties in comparison with ITQ-2 and MCM-22 prepared from the same precursor. Moreover, the catalytic behaviour and pore roles of three kinds of Mo-containing catalysts of ITQ-2-like, MCM-22 and ITQ-2 were investigated in the reaction of methane aromatization.
