摘要： 应用TPR、XRD及化学分析法研究了浸渍法制备的NiO负载在γ-Al2O3、SiO2、TiO2载体上的存在状态、最大分散度及分散规律,并对3种方法的结果作了比较,旨在为固-固吸附的研究提供一种简易有效的手段。

关键词: 浸渍法, 固-固吸附, 分散规律

Abstract: The methods of TPR, XRD phase quantitative analysis and chemical analysis were used in this paper to study systematically the existing states, maximum degree of dispersion and dispersion rules of NiOsupported on various supports including γ-Al2O3, SiO2, TiO2by impregnation, and compare the results of the three methods in order to provide a simple and effective method for studing solid-solid adsorption.

Key words: Impregnation, Solid-solid adsorption, Dispersion rules
