Maximizing the utilization of Calcium species in the supercages of CaNa-FAU zeolite for efficient CO2 capture

Carbon Dioxide Adsorption within Porous Porphyrin Networks

“…Escalating atmospheric carbon dioxide (CO 2 ) levels and their detrimental impacts on global climate have intensified the quest for efficient CO 2 capture technologies . Various porous materials, including Zeolite, activated carbon, and metal–organic frameworks (MOFs), have emerged as promising candidates for CO 2 capture. However, Zeolite faces challenges such as reduced CO 2 capture efficiency in moist conditions due to water saturation, limited pore volume, and the need for regeneration at high temperatures. , Similarly, activated carbon encounters issues related to pore engineering and low CO 2 selectivity, and MOFs are constrained in CO 2 capture under humid conditions; the metal sites within MOFs exhibit a stronger affinity for water bonding over CO 2 .…”
