Abstract

Hydrogen adsorption on chromia supported Pd, Rh and Pt was studied under various pretreatment conditions. The reduction temperature influences strongly the hydrogen uptake for all these metals. Platinum supported on chromia shows an unusually high hydrogen adsorption stoichiometry.

Abstract

Адсорбция водорода на катализаторах Pd, Rh и Pt, нанесенных на Cr2O3, изучена при различных условиях предварительной обработки. Найдено, что температура восстановления сильно влияет на поглощение водорода для всех этих металлов. Для платины на Cr2O3 наблюдалась необычно высокая стехиометрия адсорбции водорода.
