| Abstract: | In this paper,the surface diffuse reflectance ultraviolet visible spectra(DRUVS)of two and three components supported metal catalysts for methanation of CO 2 by hydrogenation were studied, and the relationship between the activity of catalytic hydrogenation and the interaction among the components of the catalysts was revealed.Based on the analysis of the DRUVS of the catalysts with defferent amount of promoters in two component catalysts system,the dependence relationship between the characteristic strength of the DRUVS and the catalytic activity was worked out. |
