a In situ DRIFTS spectra of c-Cu-34 and 9%ZnO/c-Cu-34 catalysts under 33.3% CO + 66.7% H2 (total pressure: 2 MPa) at 523 K. b In situ transmission FT-IR spectra of CO adsorption (PCO = 1000 Pa) at 123 K on various used ZnO/Cu catalysts in CO hydrogenation to methanol reaction without exposure to air, and the red and blue lines represent the fitted vibrational peaks of CO adsorbed on the Cu{111} facets and CuZn alloy, respectively. CH3OH productions over various ZnO/Cu catalysts as a function of the intensity of CO adsorbed on c Cudefective Cu(100)-Zn alloy and d Cu{111} facets derived from corresponding DRIFTS results.
