A new Cu(I)\u2010based adsorbent was synthesized and examined for the capacity of removing carbonyl sulfide (COS) from a CO<jats:sub>2<\/jats:sub> stream in an effort to solve the competitive adsorption between CO<jats:sub>2<\/jats:sub> and COS and to seek opportunity to advance adsorption capacity. A wide range of characterization techniques were used to investigate the physicochemical properties of the synthesized Cu(I) adsorbent featuring <jats:italic>\u03c0<\/jats:italic>\u2010complexation and their correlations with the adsorption performance. Meanwhile, the first principal calculation software CP2K was used to develop an understanding of the adsorption mechanism, which can offer useful guidance for the adsorbent regeneration. The synthesized Cu(I) adsorbent, prepared by using copper citrate and citric acid on the ZSM\u20105 (SiO<jats:sub>2<\/jats:sub>\/Al<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub>\u00a0=\u00a025) carrier, outperformed other adsorbents with varying formulations and carriers in adsorption capacities. Through optimization of the preparation and adsorption conditions for various adsorbents, the breakthrough adsorption capacity (<jats:italic>Q<\/jats:italic><jats:sub><jats:italic>b<\/jats:italic><\/jats:sub>) for COS was further enhanced from 2.19\u00a0mg\/g to 15.36\u00a0mg\/g. The formed stable <jats:italic>\u03c0<\/jats:italic>\u2010complex bonds between COS and Cu(I), as confirmed by density functional theory calculations, were verified by the significant improvement in the adsorption capacity after regeneration at 600\u00b0C. The above advantages render the novel synthesized Cu(I) adsorbent a promising candidate featuring cost\u2010effectiveness, high efficacy and good regenerability for desulfurization from a CO<jats:sub>2<\/jats:sub> stream.<\/jats:p>","DOI":"10.1002\/smo.20240027","type":"journal-article","created":{"date-parts":[[2025,1,5]],"date-time":"2025-01-05T04:14:02Z","timestamp":1736050442000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Development
