| 英文摘要 | the catalytic performances of zro2-based catalysts were evaluated for the synthesis of higher alcohols from synthesis gas. the crystal phase structures were characterized by x-ray diffraction (xrd) and uv raman. the results indicated that zro2 and pd modified zro2 catalysts were effective catalysts in the synthesis of ethanol or isobutanol, and their selectivities basically depended on the crystal phase of zro2 surface. the zro2 with surface tetragonal crystal phase exhibited a high activity to form ethanol, while the zro2 with surface monoclinic crystal phase exhibited a high activity to form isobutanol. temperature-programmed desorption (tpd) experiment indicated that the high activity of isobutanol formation from synthesis gas over monoclinic zirconia was due probably to the strong lewis acidity of zr4+ cations and the strong lewis basicity of o2- anions of coordinative unsaturated zr4+-o2- pairs on the surface of monoclinic zro2.
