Influence of promoter on catalytic properties of Cu-Me-Fe/ZrO_2 Catalysts for Alcohols synthesis

摘要

The addition of iron and manganese has a strong effect on the Cu/ZrO_2 catalyst performance for alcohol synthesis.The structures of catalysts have been investigated using X-ray absorption spectroscopy and diffuse reflectance FTIR spectroscopy of absorbed CO.It is found that the Cu-Fespecies and the interaction between them play an important role in converting the activity centr for methanol synthesis to the center for higher alcohols synthesis.
