摘要

By using an atom-planting method, the alumination and antimonation of dealuminated mordenite zeolites with A1C1₃ and SbC1₃ at elevated temperatures were carried out. 29_Si-MAS NMR shows that introduction of 4-coordinated aluminum atoms into the zeolite framework occurred during the alumination. The generation of both Bronsted and Lewis acid sites by the alumination are demonstrated by IR spectroscopy of adsorbed pyridine. An acidic hydroxyl band at 3663 cm⁻¹ in the IR spectrum of OH stretching vibration region was developed by the antimonation, and was assigned to a Sb(OH)Si hydroxyl in the zeolite framework.
