The structure and catalytic activity of Pt complexes heterogenized on a silica surface

The catalytic activity of complex compounds containing different metal cont ents immobilized on a silica surface towards the oxidation of carbon monoxi de and hydrogen has been investigated. In addition, the influence of the co ncentration of hydrogen and oxygen and the treatment of such catalysts by t he individual components in the reaction mixture on their catalytic activit y in the hydrogen oxidation reaction has also been studied. The structural peculiarities of platinum complexes heterogenized on a silica surface have been established by diffuse reflectance electronic spectroscopy.
