Abstract
Density functional theory with Grimme's empirical correction, DFT-D3, has been used to examine the adsorption of a carbon dioxide molecule by different sets of zeolitic imidazolate framework materials (ZIF-1 to -4, -6 to -10, and -zni). We have calculated the interaction energy, the dipole moment variation, and the charge density difference for the different CO 2 @ZIF structures. Our study shows a strong relationship between the CO 2 adsorption energy and the volume of the cavities of the ZIFs: the capture of carbon dioxide depends on the shape and size of the ZIFs pore in which CO 2 has been inserted. The physisorption phenomena that govern the adsorption of CO 2 molecule require both π-stacking interactions and hydrogen-like bonding. We have found that adsorption does not change the geometry of CO 2 , but it induces a significant structural change in some ZIF structures.
