The development of adsorbents for carbon capture and storage is expanding at a rapid rate. This article presents a novel sustainable synthesis method for the production of chitosan\/activated carbon CO2 adsorbents. Chitosan is a biopolymer that is naturally abundant and contains amino groups (\u2013NH2), which are required for the selective adsorption of CO2. Spent coffee grounds have been considered as a potential feedstock for the synthesis of activated coffee grounds through carbonization and chemical activation. The chitosan\/activated coffee ground composite microspheres were created using the emulsion cross-linking method with epichlorohydrin. The effects of the amount of chitosan (15, 20, and 25 g), activated coffee ground (10, 20, 30, and 40%w\/w), and epichlorohydrin (2, 3, 4, 5, 6, 7 and 8 g) were examined. The CO2 capture potential of the composite beads is superior to that of the neat biopolymer beads. The CO2 adsorbed of synthesized materials at a standard temperature and pressure is improved by increasing the quantity of activated coffee ground and epichlorohydrin. These findings suggest that the novel composite bead has the potential to be applied in CO2 separation applications.<\/jats:p>","DOI":"10.3390\/ijms25168916","type":"journal-article","created":{"date-parts":[[2024,8,16]],"date-time":"2024-08-16T06:23:20Z","timestamp":1723789400000},"page":"8916","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Enhanced CO2 Capture Potential of Chitosan-Based Composite Beads by Adding Activated Carbon from Coffee Grounds and Crosslinking with Epichlorohydrin"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9319-6211","authenticated-orcid":false,"given":"Vorrada","family":"Loryuenyong","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, Faculty of Engineering and Industrial Technology, Silpakorn University, Nakhon Pathom 73000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Worranuch","family":"Nakhlo","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Faculty of Engineering and Industrial Technology, Silpakorn University, Nakhon Pathom 73000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Praifha","family":"Srikaenkaew","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Faculty of Engineering and Industrial Technology, Silpakorn University, Nakhon Pathom 73000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Panpassa","family":"Yaidee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Faculty of Engineering and Industrial Technology, Silpakorn University, Nakhon Pathom 73000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1948-5218","authenticated-orcid":false,"given":"Achanai","family":"Buasri","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Faculty of Engineering and Industrial Technology, Silpakorn University, Nakhon Pathom 73000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2090-7334","authenticated-orcid":false,"given":"Apiluck","family":"Eiad-Ua","sequence":"additional","affiliation":[{"name":"College of Materials Innovation and Technology, King Mongkut\u2019s Institute of Technology Ladkrabang, Bangkok 10520, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Oliveira, M.R., Cecilia, J.A., Ballesteros-Plata, D., Barroso-Mart\u00edn, I., N\u00fa\u00f1ez, P., Infantes-Molina, A., and Rodr\u00edguez-Castell\u00f3n, E.
