文摘

Experimental adsorption data for Rh precursors on mesoporous silica reported. Adsorption isotherms depend strongly on CO2 density. Adsorption equilibria on the substrate characterized by the Dubinin-Astakhov equation. Trend of model parameters allows preparation of desired impregnated materials.
