•Synthesis of the micro-mesoporous composite materials of ZSM-12/MCM-48 type.•Application of these adsorbents in the carbon dioxide adsorption.•Effects of the contents of zeolite and amino group in the material surface on the CO2 capture efficiency.
In this study ZSM-12/MCM-48 adsorbents have been synthesized at three ZSM-12 content, and also were functionalizated with amine groups by grafting. All the adsorbents synthesized were evaluated for CO2 capture. The X-ray diffraction analysis of the ZSM-12/MCM-48 composite showed the main characteristic peaks of ZSM-12 and MCM-48, and after the functionalization, the structure of MCM-48 on the composite impregnated was affected due amine presence. For the composites without amine, the ZSM-12 content was the factor determining in the adsorption capacity of CO2 and for the composites with amine the amount of amine was that influenced in the adsorption capacity.
