英文摘要: ZrO2-A and ZrO2-B catalysts were prepared by two different coprecipitation methods and their performance of CO hydrogenation was studied. The results indicated that ZrO2 and Li-, Pd- and Mn-modified ZrO2 catalysts exhibited good selectivity and high STY to higher alcohols. The surface characteristics of ZrO2-A and ZrO2-B samples were investigated by means of BET, NH3-TPD, XRD and UV Raman technique. The tetragonal zirconia on the surface region of ZrO2-A and Li-Pd-Mn/ZrO2-A catalysts may be responsible for the high selectivity towards ethanol, while the monoclinic zirconia on the surface of ZrO2-B and Li-Pd-Mn/ZrO2-B catalysts may be crucial to the high isobutanol selectivity.
