【摘要】 采用类凝胶 超临界流体干燥法制备了超细Mo Co K催化剂 ,并运用TEM和选区电子衍射技术对制得的催化剂进行了表征。结果表明 ,制得的催化剂由属于超细粒子范畴的片状微晶和球状小颗粒组成 ,进一步经选区电子衍射技术分析 ,前者归属为MoO3 物相 ,后者归属为CoMoO4 物相更多还原

【Abstract】 Ultrafine Mo Co K catalysts were prepared by the "gel like" method followed by supercritical fluid drying technique. The types of particles were observed in the TEM micrograph: one was pellet shaped micro crystallites and the other was ball like small particles. The electron diffraction result indicated that the former corresponded to MoO 3 and the latter corresponded to CoMoO 4.更多还原
