Carbon capture from large sources and ambient air is one of the most promising strategies to curb deleterious effect greenhouse gases. Among different technologies, CO2 adsorption has drawn widespread attention mostly because its low energy requirements. Considering that water vapor a ubiquitous component in almost all CO2-rich industrial gas streams, understanding impact on critical importance. Owing diversity adsorbents, plays many roles severe inhibitor an excellent promoter. Water may also increase rate or have opposite effect. In presence amine-containing even necessary for their long-term stability. The current contribution comprehensive review effects whether feed as adsorbent moisture adsorption. For convenience, we discuss over four broadly defined groups materials separately, namely (i) physical including carbons, zeolites MOFs, (ii) amine-functionalized (iii) reactive metal carbonates oxides. each category, humidity level uptake, selectivity, kinetics under operational conditions are discussed. Whenever possible, findings compared, paying particular both similarities inconsistencies. completeness, membrane separation discussed, albeit briefly.
