Abstract
Electronic behavior of different structure zeolites containing silver species was studied by X-ray photoelectron spectroscopy (XPS). Three different microporous zeolite structures in sodium form, Mordonite (NaMOR), Faujasite (NaY) and Linde Type A (NaA) were loaded with silver (Ag) by ion exchange method. The characterization of materials was also performed by X-ray diffraction (XRD) and chemical analysis. The results indicate that silver was interchanged in the structure of the zeolites. From XRD data the introduction of silver in zeolites increases the average of the crystallite size. X-ray photoelectron spectroscopy measurements of silver zeolites were made and Auger parameters for different chemical states of silver have been derived based upon these measurements. XPS analysis confirms different oxidation states of silver species present in zeolite structures.
