| Abstract: | The addition of iron and manganese has a strong effect on the Cu/ZrO2 catalyst performance for alcohols synthesis. The structures of catalysts have been investigated using X-ray adsorption spectroscopy and diffuse reflectance FTIR spectroscopy of absorbed CO. It is found that the Cu-Fe species and the interaction between them play an important role in converting the activity center for methanol synthesis to the center for higher alcohols synthesis.This revised version was published online in December 2005 with corrections to the Cover Date. |
