Abstract

Small copper particles within zeolite (mordenite) matrix produced by copper ion reduction were studied. Variation of SiO₂/Al₂O₃ molar ratio of mordenite does not change crystal structure, but results in different ionic properties. A change of SiO₂/Al₂O₃ ratio leads to transformation of the plasmon resonance from a classical peak to a shoulder in the same wavelength range. These features were simulated by the Mie theory, and calculations outlined additional absorption bands those consistent with the experiment.
