Particle size dependence for CO chemisorption on supported Ru catalysts

Reaction Kinetics and Catalysis Letters Aims and scope Submit manuscript

Abstract

The stoichiometry of CO chemisorption on highly dispersed zeolite-supported Ru has been investigated. This stoichiometry, which can be expressed as CO/H, increases with decreasing Ru particle diameter. For diameters <1.6 nm this ratio approached a limiting value of 4–5, indicating the formation of surface carbonyls. No direct influence of the support on this ratio could be detected.

Abstract

Была исследована стехиометрия хемосорбдии CO на высокодисперсном Ru, нанесенном на цеолиты. Эта стехиометрия, выражаемая отношением CO/H, увеличивается с уменьшением диаметра частиц Ru. Для диаметров <1,6 nм это отношение достигает предельной величины 4–5, указывая на образование поверхностных карбонилов. Не было детектировано никакого непосредственного влияния носителя на это отношение.
