WebMar 7, 2024 · The relatively high activity of SnO 2 in the low temperature range was strictly limited by the concentration of adsorbed O − species. During CO oxidation, their concentration quickly and irreversibly decreases. Thus, all modifications of tin dioxide which enable oxygen adsorption at low temperatures will promote CO oxidation over SnO 2. WebSep 4, 2013 · The preferential adsorption site is identified as a 'bridge' type site between the cluster entities exposed at the (001) surface termination. The Al-O bonding between the adsorbate and the substrate presents a covalent character, with s-p hybridization occurring between the states of the adsorbed oxygen atom and the aluminum atoms of the surface. download 64-bit nitro pro installer
