ABSTRACT:

Supported bimetallic cluster catalysts provide useful systems for fundamental catalytic investigations. The term 'bimetallic cluster' applies to systems composed of two metals that do not form bulk alloys.  The aim of the work presented was to examine a series of silica supported bimetallic catalysts using reactor studies and to then extend the work to include nuclear magnetic resonance (NMR) studies. With NMR we probed the chemical and structural properties of adsorbed species and decomposition products at pressures much higher than possible in ultrahigh vacuum experiments.
