Preparation of nanostructured gold films and analysis of their catalytic properties

详细

Gold films are obtained by thermal evaporation in different media: vacuum, hydrogen, and krypton. The structure of the films obtained, and their adsorption and catalytic properties in molecular hydrogen reactions are studied in a wide temperature range. It is found that gold films with a special structure can adsorb hydrogen and exhibit catalytic activity in reactions with molecular hydrogen under cryogenic conditions. Differences in the structure and catalytic properties of the gold films depending on the preparation conditions are shown.
