Abstract

Hydrogen-oxygen titration and carbon monoxide adsorption on Ru/Al2O3 samples were employed to determine metal dispersity values. To avoid Ru−CO polycarbonyl formation, before CO adsorption, the ruthenium surface was precovered with hydrogen. By this procedure, good agreement between H2−O2 titration, CO adsorption and electron microscopy is obtained.

Abstract

Дисперсность металла для образцов Ru/Al2O3 была определена титрованием H2−O2 и адсорбцией CO. Во избежание образования поликарбонилов Ru−CO, поверхность рутения заполняется водородом. Такая процедура дает хорошее согласие между данными титрования H2−O2, адсорбции CO и электронной микроскопии.
