Interaction of CO over the pre-reduced (0.35)Cu-MFI(11.5) sample. (a) Effect of increasing pressure of CO (from black to orange). (b) Effect of outgassing on the sample exposed to 192 mbar of CO (from orange to red). (c) Effect of CO on the OH stretching modes. (d) Effect of CO on the perturbation of framework modes by Cu.
