Catalytically active gold clusters and nanoparticles for CO oxidation / A. N. Pestryakov [et al.]
Уровень набора: Surface science = 1964-Язык: английский.Страна: .Резюме или реферат: Electronic states of gold nanoparticles in mordenite and their transformations under redox treatments have 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 channels and on the external surface of the zeolite - Au+ and Au3+ ions, charged clusters Audю n , and neutral nanoparticles Aum. Catalytic tests of the samples revealed the existence of two types of active sites of gold in CO oxidation - gold clusters <2 nm (low-temperature activity) and gold nanoparticles (high temperature activity)..Примечания о наличии в документе библиографии/указателя: References: p. 3795 (26 tit.).Аудитория: .Тематика: труды учёных ТПУECOSS-24, Proceedings of the 24th European Conference on Surface Science
