| सारांश: | Title screen The nature of different Au species supported on hexagonal mesoporous silica has been studied by infrared spectroscopy of adsorbed CO. Experiments revealed existence of the following states ofsupported gold: neutral metal particles Au°, ions Au+ and a number of partly charged states Auδ+ with different effective charge. Redox pretreatments (vacuum, O2 and H2) of Au/SiO2 at the different temperatures (100, 300 and 500°C) exert a significant effect on the electronic state of supported Au species. The experiments showed high stability of Auδ+ states under all treatments; that may prove their active role in catalytic properties of gold Режим доступа: по договору с организацией-держателем ресурса |
