Magnesium oxide has been introduced into zeolites MCM-22, MCM-36, IPC-3, IPC-3PI and ITQ-2 synthesized from 2D layered precursors MCM-22P and ICP-3P. Prepared materials were tested as carbon dioxide adsorbents in the temperature range from 0 °C to 60 °C. For parent zeolites, the IPC-3 has shown at 1 kPa the adsorption capacity (5.1 cm3/g STP), which was nearly two times higher than that of MCM-22 (2.7 cm3/g STP). Adsorption capacity of zeolites in the low pressure region markedly increased due to incorporation of magnesium oxide. The amount adsorbed on MgO-IPC-3 and MgO-MCM-22 at 1 kPa was enhanced to 11.4 and 13.7 cm3/g STP. Isosteric adsorption heats giving information on the energetics of CO2 adsorption were calculated.
