“…Trace amounts of moisture content of approximately 20 ppm from the feeding gas CO 2 have the potential to be a precursor and enhance the formation of more surface hydroxyl groups on the ready presence of the hydroxyl before adsorption. To promote formation of the bicarbonate species, hydroxyl groups can be increased by treating iron oxides with water vapor. , …”

“…To promote formation of the bicarbonate species, hydroxyl groups can be increased by treating iron oxides with water vapor. 37,38 However, adsorption at room temperature and pressure shows no adsorption bands for monodentate and bidentate carbonate on Fe 2 O 3 . These carbonate species form by interaction between the surface oxygen of the Fe atom and CO 2 to produce monodentate carbonate and bidentate carbonate.…”

Various type iron oxides of FeO, Fe2O3, and Fe3O4 were used for carbon dioxide (CO2) capture at room temperature and pressure by studying its adsorption–desorption properties. Several interactions of carbonate species were detected on its surface. The morphology of carbonate formation shows different structures on FeO (grooves-like), Fe2O3 (fine sharp particles), and Fe3O4 (aggregated nanoparticles). CO2 chemisorption discovered a potential adsorbent of Fe2O3 with an adsorption capacity of 3.95 mgCO2/gadsorbent. The adsorption capacity increased up to 62.8% by using concentrated 99.9% CO2 for adsorption. At higher concentration of CO2 exposure, it partially turns to red color which indicated the less stable Fe3O4 was easily oxidized to Fe2O3 after CO2 regeneration with temperatures up to 500 °C. Hence, Fe2O3 possessed the highest basicity strength (1.26 cm3/g), and the adsorption capacity after four cycles was not significantly reduced by 8.6% indicating an effective chemical or physical adsorption in CO2 capture.

A technology using calcium oxide (CaO)‐based sorbents for CO2 capture has been identified to be the optimal candidate for capturing CO2 at high temperature. Realistic gases always contain water vapor and many other components, and it has been reported that these wet conditions have a non‐negligible influence on the performance of the sorbent. This Review outlines the role of H2O during the CO2 capture process using CaO‐based sorbents. The role of steam/H2O in sorbent reactivation, the effect of steam on carbonation and calcination, and the influence of steam when simultaneously existing in both carbonation and calcination stages are discussed. It is suggested that injection of steam in both carbonator and calciner is a good strategy to achieve better reactivity of the CaO‐based sorbent for CO2 capture. The mechanisms of the effect of steam in carbonator and calciner on CO2 capture are also discussed. The Review concludes with future research directions.
