摘要
Two CuNiMnZrO_2 catalysts (crystallized or non-crystallized) were prepared byco-hydrolyzing zirconium n-propoxide with Cu(NO_3)_2, Mn(NO_3)_2 and Ni(NO_3)_2 in an ethanolsolution in the presence of diglycol. The physical and chemical properties of the catalysts werecharacterized using BET, XRD, TEM, XPS and CO-DRIFT techniques. It was found that thenon-crystallized CuNiMnZrO_2 catalyst demonstrated highly dispersed active phases and high activityfor CO adsorption, which resulted in good performance for synthesis of higher alcohols in COhydrogenation compared to crystallized CuNiMnZrO_2.
