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
