    Notes: Abstract The bond energies of oxygen have been determined by thermodesorption from Period IV transition metal oxides, both after treatment with oxygen and under steady state conditions of the catalytic oxidation of CO. With the exception of V2O5, there are several (2–3) forms of adsorbed oxygen with different bond energies on the surface of the oxide treated with oxygen.

    Description / Table of Contents: Abstract На основании кинетических закономерностей изотопного обмена установлено, что гетерообмен O2 на поверхности окислов осуществляется по двум различным механизмам: 1) за счет обратимой адсорбции с образованием двух атомных форм с различной прочностью связи и 2) через трехатомный комплекс из молекулы и поверхностного атома кислорода. Наяду с этим, может протекать гомообмен молекулярного кислорода по ассоциативному механизму.
    Notes: Abstract On the basis of the kinetic law of isotope exchange, it has been established that the heteroexchange of O2 occurs via two different mechanisms: 1/reversible adsorption resulting in the formation of two atomic species with different bonding strengths, and 2/formation of a triatomic complex from the oxygen molecule and an oxygen atom on the surface. Simultaneously, the homoexchange of molecular oxygen may take place by an associative mechanism.

    Description / Table of Contents: Abstract Молекулярный кислород адсорбируется на поверхности золота при повышенных температурах, T≥900 К. При этом образуется поверхностный окисел золота, не разлагающийся в вакууме при T=1000 К. Атомарный кислород адсорбируется при T=300 К и полностью десорбируется с поверхности при T=500–600 К (Едес=12–15 ккал/моль), не переходя в кислород поверхностного окисла.
    Notes: Abstract Molecular oxygen adsorbs on gold surfaces at elevated temperatures (T≥900 K) forming a surface gold oxide which does not decompose in vacuum at T=1000 K. Atomic oxygen adsorbs at T=300 K and completely desorbs from the surface at T=500–600 K (Edes=12–15 kcal/mol) without trandformation to surface oxide oxygen.

    Description / Table of Contents: Abstract Удельная каталитическая активность нанесенного серебра при эквивалентом соотношении реагантов приблизительно в 10 раз ниже удельной активности серебряного порошка. Этот эффект обусловлен воздействием реакционной среды на катализатор: в условиях реакции микрокристаллы серебра глубоко окисляются и теряют активность. В стационарном состоянии реакция протекает главным образом на крупных серебра, сохраняющих в условиях реакции металлическое состояние.
    Notes: Abstract The specific catalytic activity of supported silver at equivalent amounts of reagents is approximately 10 times lower than that of silver powder. This is due to the influence of the reaction medium on the catalyst: under the reaction conditions, microcrystals of silver are extensively oxidized and lose their activity. In the steady state the reaction proceeds mainly on large silver crystallites, which remain in the metallic state under reaction conditions. At excess carbon monoxide, no significant influence of the metal dispersity on the catalytic activity is observed.
