Abstract

H2 and O2 uptakes at 296 K on a Pt/Al2O3 catalyst remained constant during repeated H2−O2 titration cycles conducted in a high vacuum adsorption system. Previously reported variations in these uptakes are attributed to adsorption of contaminants during desorption conditions. Also, it was found that nearly 40% of the H2 adsorbed could be removed by degassing at 296 K for 1 hr.

Abstract

Поглощение H2 и O2 при 296 К на катализаторе Pt/Al/2O3 остается постоянным при повторных циклах титрования H2−O2, проводимых в адсорбционной системе высокого вакуума. Первоначально сообщенные изменения в присоединении приписываются адсорбции загрязнения в условиях десорбции. Также было найдено, что около 40% адсорбированного H2 может быть удалено за 1 час с откачки при 296 К.
