In particular, low-cost materials that can be regenerated at low temperatures would overcome the limitations of current technologies. In this work, we introduce a new class of designer sorbent materials known as \u201ccharged-sorbents\u201d. These materials are prepared through a battery-like charging process which accumulates ions in the pores of low-cost activated carbons, with the inserted ions then serving as adsorption sites for carbon dioxide adsorption. We use our charging process to accumulate reactive hydroxide ions in the pores of a carbon electrode, and find that the resulting sorbent material can rapidly capture carbon dioxide from ambient air via (bi)carbonate formation. Unlike traditional bulk carbonates, charged-sorbent regeneration can be achieved at low temperatures (90-100 \u00baC), and the sorbent&rsquo;s conductive nature permits direct Joule heating regeneration2,3 using renewable electricity. Given their highly tailorable pore environments and low cost, we anticipate that charged-sorbents will find numerous potential applications in chemical separations, catalysis, and beyond.<\/p>\n","protected":false},"excerpt":{"rendered":"<h4>DOI:<\/h4>\n<div class=\"b-doi\">10.26434\/chemrxiv-2023-p4fhz-v2<\/div>\n<h4>Authors:<\/h4>\n<div class=\"b-author\">Huaiguang Li, Mary E.
