The performance of the three Ionosolv\u2010ILs triethylammonium hydrogen sulfate ([TEA][HSO\n                    <jats:sub>4<\/jats:sub>\n                    ]),\n                    <jats:italic>N<\/jats:italic>\n                    ,\n                    <jats:italic>N<\/jats:italic>\n                    \u2010dimethylbutylammonium hydrogen sulfate ([DMBA][HSO4]), and tributylmethylphosphonium methyl sulfate ([TBMP][MeSO\n                    <jats:sub>4<\/jats:sub>\n                    ]), mixed with methanol (MeOH) (30\/70 wt%), is evaluated by methyl formate yield from extracted hemicellulose and lignin as well as purity of the bleached cellulose pulp in the presence of various Keggin\u2010type POMs. The redox\u2010balanced H\n                    <jats:sub>8<\/jats:sub>\n                    PVMnMo\n                    <jats:sub>10<\/jats:sub>\n                    O\n                    <jats:sub>40<\/jats:sub>\n                    POM catalyst in [TBMP][MeSO\n                    <jats:sub>4<\/jats:sub>\n                    ]\/MeOH emerge as the most effective combination, achieving 20% methyl formate yield from commercial beech wood. The glucan content in the bleached cellulose\u2010enriched solid consisted is over 90%, demonstrating that the use of MeOH drastically improved lignin extraction in parallel with full hemicellulose extraction. The cellulose is highly susceptible to enzymatic hydrolysis, generating a pure and concentrated cellulosic glucose stream. The formed solid catalyst complex is examined in detail to reveal its chemical nature as POM\u2010IL\u2010complex. The approach is applicable to disparate types of lignocellulosic biomass, including hardwood, softwood, and grass.\n                  <\/jats:p>","DOI":"10.1002\/cssc.202501034","type":"journal-article","created":{"date-parts":[[2025,9,10]],"date-time":"2025-09-10T12:11:36Z","timestamp":1757506296000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Boosting POM\u2010Ionosolv Biorefining of Lignocellulosic Biomass by Using Redox\u2010Balanced Polyoxometalate Catalysts in Methanolic Ionic Liquid Reaction Media"],"prefix":"10.1002","volume":"18","author":[{"given":"Stefanie","family":"Wesinger","sequence":"first","affiliation":[{"name":"Institute of Technical and Macromolecular Chemistry University of Hamburg  Bundesstra\u00dfe 45 20146 Hamburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Rabiner","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering Imperial College London  Bone Building, South Kensington Campus London SW7 2AZ UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suhaib","family":"Nisar","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering Imperial College London  Bone Building, South Kensington Campus London SW7 2AZ UK"},{"name":"Department of Chemistry Imperial College London Molecular Sciences Research Hub  White City Campus, 82 Wood Lane W12 0BZ UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonhard","family":"Schill","sequence":"additional","affiliation":[{"name":"Department of Chemistry Technical University of Denmark  Kemitorvet, 207 2800 Kgs.
