Abstract

ZnCHA was successfully synthesized, and their potentials for CO2 capture under different conditions were also evaluated for the first time. Furthermore, SrCHA, CaCHA and MgCHA chabazite were also prepared for comparison purposes. The structure and morphology of cation-exchanged chabazites were characterized with various experimental techniques such as XRD, SEM and XRF. The CO2 and N2 adsorption isotherms on chabazites was also investigated, demonstrating that ZnCHA exhibited larger CO2/N2 selectivity comparing to CaCHA, MgCHA and SrCHA at 273 and 298 K.
