The deposition of such clusters on metal oxide supports and the subsequent removal of the organic ligands under different conditions were monitored in-situ via FTIR spectroscopy. The resulting catalysts were further characterized via HRTEM and chemisorption measurements and were examined for a number of catalytic reactions including the SCR of NO by propylene, the 16O:18O exchange reaction, the oxidation of CO in the presence and absence of hydrogen, the hydrogenation and the oxidation of propylene, and the hydrogenolysis of ethane. The use of organometallic cluster precursors could lead to the synthesis of unique bimetallic catalysts, exhibiting close contact between the different metal components, a narrow distribution of metal particle sizes, and different catalytic properties than conventionally-prepared supported metal catalysts. This is an abstract of a paper presented at the 231th ACS National Meeting (Atlanta, GA 3/26-30/2006).
