A loading with trimethylphosphine oxide (TMPO) is sensitive to weaker Lewis acid sites (LAS). A subsequent hydration changes the nature of water\u2010accessible boric acid surface species. Conversion of methanol, ethanol, or ethene over boric acid\u2010modified MFI was tested. For 1.5 wt% loading, an increased BTEX content and lifetime in ethanol conversion was observed, while other modified catalysts were outperformed by the unmodified parent. Most boron is removed after catalytic application. It is concluded that the introduced weak surface acidity and the introduced LAS density could render the modification method interesting for synthesizing new adsorbents operated at moderate conditions.\n                  <\/jats:p>","DOI":"10.1002\/chem.202503502","type":"journal-article","created":{"date-parts":[[2026,2,21]],"date-time":"2026-02-21T09:55:45Z","timestamp":1771667745000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Boric Acid Post\u2010Modified [Al]ZSM\u20105 Zeolites: Properties, Acidity, and Ethanol\/Ethene Conversion"],"prefix":"10.1002","volume":"32","author":[{"given":"Zheng","family":"Li","sequence":"first","affiliation":[{"name":"Institute of Chemical Technology University of Stuttgart  Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Dittmann","sequence":"additional","affiliation":[{"name":"Institute of Chemical Technology University of Stuttgart  Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dennis","family":"Strassheim","sequence":"additional","affiliation":[{"name":"Institute of Chemical Technology University of Stuttgart  Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8883-1145","authenticated-orcid":false,"given":"Michael","family":"Dyballa","sequence":"additional","affiliation":[{"name":"Institute of Chemical Technology University of Stuttgart  Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,2,21]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0167\u20102738(00)00632\u20109"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ssnmr.2011.03.007"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.micromeso.2004.10.035"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.micromeso.2006.07.034"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.micromeso.2024.113353"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/cite.201300066"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5CS00109A"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1039\/C8CY01032C"},{"key":"e_1_2_7_10_1","unstructured":"W.
