There is a lack of consensus on the charge state of active gold species in catalytic CO oxidation reaction. Herein, Au/SBA-15 catalyst was prepared by room temperature ozone treatment. Through diffuse reflectance Fourier-transform infrared spectroscopy (DRIFTS), two different gold species, Au0 and Auδ- with CO adsorption at about 2112 cm-1 and 2077 cm-1, were observed on Au/SBA-15. In CO oxidation mixture, the 2077 cm-1 band is completely attenuated while the 2112 cm-1 band retains some intensity. CO-Auδ- bonding
