用透射电子显微术(TEM),微衍射技术(MICRODIFF)、高分辨电子显微术(HREM)对中科院山西煤化所Zno/Cr_2O_3系催化剂进行了初步结构表征,得出了电子衍射谱及相应的高分辨条纹象。井与其X衍射结果及M.D.CONCA.等得出的Zn-Cr混合氧化物催化剂的XRD结果进行了对比,初步认为二者从晶系,点阵常数,及X-衍射谱等都较接近,从而为该催化剂进一步的微观结构研究提供了依据。为揭示其反应性能与结构 The primary structure characterization of Zno / Cr 2 O 3 catalysts was carried out by transmission electron microscopy (TEM), micro-diffraction (MICRODIFF) and high-resolution electron microscopy (HREM) High Resolution Streaks Icon. XRD results of Zn-Cr mixed oxide catalysts obtained from their X-ray diffraction results and MDCONCA. The results show that they are closer to the crystal system, the lattice constant, the X-ray diffraction spectrum and so on The catalyst for further study of the microstructure provided the basis. To reveal the reaction performance and structure
