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