Resumo: Abstract The adsorption capacity of CO2 in mesoporous materials with different structures was evaluated. For this purpose, MCM-48 and SBA-15 impregnated with nickel in proportions of 5, 10 and 20 wt% were used. The results showed that impregnation of nickel promoted an increased interaction between CO2 and the surface of the material. Data were fitted using the Freundlich model. Gibbs free energy and entropy changes of the adsorption system were evaluated. Thermodynamics of adsorption showed that the process is spontaneous. From the Freundlich model, it was concluded that there is a strong interaction of CO2 with sites of the impregnated materials.
