CO₂ Adsorption Capacities in Zeolites and Layered Double Hydroxide Materials.

ABSTRACT: The development of technologies that allow us to reduce CO₂ emissions is mandatory in today's society. In this regard, we present herein a comparative study of CO₂ adsorption over three types of materials: zeolites, layered double hydroxides (LDH), and zeolites coated LDH composites. The influence of the zeolite Si/Al ratio on zeolites sorption capacity along with the presence of mesopores was investigated. By comparing these results with the well-known performance of LDHs, we aim to provide insights on the factors that may influence the CO₂ capture capacity over zeolites, thus providing useful tools for tuning their properties upon post-treatments.
