In recent years, the important role of metal-support interface in Au catalysis has been documented for various reactions, ranging from CO oxidation, selective hydrocarbon oxidation, to alcohol decomposition.  Recently, Au atomic clusters stabilized by intermediates formed in the reaction are found to be important in selective liquid phase hydrocarbon oxidation.  Interestingly, for these reactions, the function of Au is not the traditional lowering of the activation barrier for the transformation of reactant to product, but in facilitating the formation of an initiator for the catalytic cycle that may occur without participation from Au.  Examples from our laboratory illustrating these two modes of operation of Au clusters will be presented.<br/>
