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.
Удельная каталитическая активность нанесенного серебра при эквивалентом соотношении реагентов 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.
