Supported Molecular Iridium Clusters for Ethylene Hydrogenation

Supported Molecular Iridium Clusters for Ethylene Hydrogenation 

Two effects were noted in this study with regard to nudearity and support effects [52]. Ir4 dusters versus mononuclear Ir spedes had faster rates for both ethylene hydrogenation and H-D exchange reactions on both supports. The explanation for this was that the Ir duster had more metal surface area available for both hydrogen dissodation and activation of the ethylene on nearby metal sites - two required processes for catalysis - relative to the mononudear Ir complexes [52].
