Spectroscopic Observation of Dual Catalytic Sites During .

The prevailing view of CO oxidation on gold-titanium oxide (Au/TiO2) catalysts is that the reaction occurs on metal sites at the Au/TiO2 interface. We observed dual catalytic sites at the perimeter of 3-nanometer Au particles supported on TiO2 during CO oxidation. Infrared-kinetic measurements indicate that O-O bond scission is activated by the formation of a CO-O2 complex at dual Ti-Au sites .
