摘要: 本文用分子探针法测定、研究了NiO-Cr2O3-SiO2和NiO-SiO2催化剂的表面吸附中心结构,且通过逐步溶解分析、X-衍射法、TPD、磁分析等测试方法证实用该法所得结论的正确。表明这是一种研究催化剂表面吸附中心结构的新的有效方法。其特点是能在接近实际的反应条件下,快速、方便地获得催化剂表面吸附中心的结构信息。

Abstract: This paper describes how the surface structure of the catalysts of the systems NiO-SiO2 and NiO-Cr2O3-SiO2 is studied and determined by using the molecule probe method.The conclusions obtained with the method have been verified to be correct by means of TPD, X-ray diffraction and magnetic analyses etc. And as a result the method is proved to be a new effective one for studing the surface structure.This method is characterized by rapidly gathering information about surface structure of adsorption centre of catalysts in a convenient way under Closely practical conditions of reaction.
