Abstract

The formation of gold nanoparticles in mordenites has been studied by the methods of FTIR spectroscopy of adsorbed CO and diffuse reflectance UV-visible spectroscopy. Different states of ionic and metallic gold were detected in the zeolite cavities and on the external surface of the zeolite - Au+ and Au3+ ions, charged clusters Aunδ+, and neutral nanoparticles Aum. The relative amount of these states depends on the method of sample preparation, type of redox treatment and the SiO2/Al2O3 molar ratio.
