Recently, a series of studies have shown that for single crystal samples, there is no change in turnover frequency for the ethane hydrogenolysis reaction as copper is added to a ruthenium surface. This is in contrast to earlier work using the silica supported bimetallic catalysts, where a geometric effect had been proposed to account for the apparent decrease in turnover frequency with increasing copper content. The authors discuss how, in order to investigate these differing results, a series of silica supported ruthenium-group Ib metal catalysts was prepared, ensuring that no chlorine was present in the final samples. Catalysts containing silver and gold were characterized using hydrogen chemisorption. This method, however, is not applicable to copper containing catalysts due to hydrogen spillover to the copper. In this case solid state NMR of adsorbed hydrogen was used to determine the number of active ruthenium sites.
