Here, oxidative depolymerization of poplar lignin was coupled with cross\u2010flow nanofiltration using reduced\u2010graphene\u2010oxide (rGO) membranes (molecular\u2010weight cut\u2010off or MWCO\u2009\u2248\u2009470\u2009Da). Across six depolymerization liquors spanning pH 2.5\u20139.2 and distinct catalytic histories (of polyoxometalate (POM), NaOH, graphene oxide, and control), rGO membranes consistently rejected \u226590% of the &gt;1.6\u2009kDa fraction, while feed pH governed LMW partitioning. Acidic liquors favored a steric\u2010sieving regime that enriched aliphatic and aromatic monomers in the permeate (separation factors \u22485\u20136 relative to the high\u2010MW fraction), whereas alkaline conditions induced electrostatic exclusion, co\u2010retaining anionic acids with oligomers and suppressing monomer enrichment. Mechanistic studies with model mixtures showed that dilution sharpened selectivity by mitigating concentration polarization and ionic\u2010strength screening and that aromatics can modulate charge\u2010based exclusion through competitive interactions within graphitic nanochannels. Continuous diafiltration of the monomer\u2010rich liquor for 250\u2009h sustained stable flux (~11\u2009\u00b1\u20091\u2009L\u2009m\n                    <jats:sup>\u22122<\/jats:sup>\n                    \u2009h\n                    <jats:sup>\u22121<\/jats:sup>\n                    ) and selectivity, enabling complete recovery of aliphatic and aromatic monomers and LMW fractions while concentrating high\u2010MW fractions. These results establish rGO membranes as a robust, water\u2010based separation platform for MW\u2010resolved lignin fractionation.\n                  <\/jats:p>","DOI":"10.1002\/cssc.71123","type":"journal-article","created":{"date-parts":[[2026,10,20]],"date-time":"2026-10-20T11:00:51Z","timestamp":1792494051000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Graphene Oxide Membranes for Recovery of Catalytically Depolymerized Lignin Monomers and Oligomers"],"prefix":"10.1002","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8100-0284","authenticated-orcid":false,"given":"Natechanok","family":"Yutthasaksunthorn","sequence":"first","affiliation":[{"name":"School of Chemical &amp;
