Various Mn-modified CuFeZrO2 catalysts for higher alcohols synthesis were characterized and tested by TPR, DRIFT, CO hydrogenation and reactive chemisorption of N2O.It was found that suitable addition of Mn could improve the catalytic activity and C2＋ alcohols selectivity and suppress the formation of methane. TPR results showed that the reduction of CuO in CuMnFeZrO2 catalyst became more difficult because of the interaction between Cu and Mn. And such interaction proceeded stronger with the amount of Mn increased. This fact is correlated with the change of Cu surface areas and dispersion. In situ DRIFT displayed CO adsorption on the CuMnFeZrO2 catalysts. It was also shown that the interaction between Cu and Mn had occurred, the CO adsorption on the catalysts was increased and blue shifted.
