Cyclic CO2 chemisorption-desorption behavior of Na2ZrO3: Structural, microstructural and kinetic variations produced as a function of temperature

A CO2 chemisorption-desorption analysis was performed in the Na2ZrO3-CO2 system. Different cyclic experiments were performed between 500 and 800 °C and the results showed high CO2 chemisorption efficiencies. Nevertheless the Na2ZrO3 composition and microstructure evolved during the cycles.
