Herein, we present a chemically programmable, dual\u2010functional graphene oxide (GO) membrane for highly selective tritium removal under ambient conditions. By interfacially co\u2010assembling carboxyl\u2010 (\u2500COOH) and sulfonic acid\u2010functionalized (\u2500SO\n                    <jats:sub>3<\/jats:sub>\n                    H) GO, a mixed membrane (MIX) was constructed to synergistically regulate interfacial chemistry and nanoconfined transport. The MIX membrane delivers a single\u2010pass tritium removal efficiency exceeding 21% and a separation factor , while maintaining an exceptional water permeability (), significantly outperforming single\u2010functionalized counterparts. Mechanistic studies reveal that \u2500COOH domains drive the hydration\u2010assisted interfacial enrichment of tritiated water (HTO), whereas \u2500SO\n                    <jats:sub>3<\/jats:sub>\n                    H sites provide strong adsorption stabilization to facilitate reversible isotope exchange. Furthermore, operation\u2010induced interlayer expansion maximizes active site accessibility. This work demonstrates a cooperative strategy integrating interfacial chemistry and nanoconfinement engineering in 2D membranes, offering a low\u2010energy, high\u2010throughput platform for the remediation of tritiated radioactive\u00a0wastewater.\n                  <\/jats:p>","DOI":"10.1002\/smtd.70767","type":"journal-article","created":{"date-parts":[[2026,7,3]],"date-time":"2026-07-03T06:36:41Z","timestamp":1783060601000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Confinement\u2010Amplified Tritiated Water Clean\u2010Up in Functionalized Graphene Oxide Nanochannels"],"prefix":"10.1002","volume":"10","author":[{"given":"Guoyu","family":"Wen","sequence":"first","affiliation":[{"name":"Nuclear Power Institute of China Chengdu Sichuan P.
