In this study, we prepared mesoporous ZSM-5 catalysts, named ZSM5-MT(x), from commercial ZSM-5 (Si\/Al = 15), using a two-step micelle-templating procedure with octadecyltrimethylammonium bromide as a surfactant in basic medium (x = NaOH\/Si). These materials were used as catalysts for the alkylation of toluene by methanol at a low contact time to avoid thermodynamic equilibrium of the xylene isomers. Compared to the parent ZSM-5, the mesoporous ZSM5-MT(x) catalysts did not improve the para-xylene selectivity, revealing that the strategy of increasing diffusion in the catalyst is not a good strategy to follow. However, ZSM5-MT(0.5) showed less deactivation on stream than the parent ZSM-5. Therefore, introducing mesopores to ZSM-5 could be interesting to explore, combined with another strategy of shape selectivity, such as the passivation of the external surface acidity.<\/jats:p>","DOI":"10.3390\/ma16216872","type":"journal-article","created":{"date-parts":[[2023,10,26]],"date-time":"2023-10-26T07:22:15Z","timestamp":1698304935000},"page":"6872","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Influence of the Mesoporosity of Hierarchical ZSM-5 in Toluene Alkylation by Methanol"],"prefix":"10.3390","volume":"16","author":[{"given":"Lucie","family":"Desmurs","sequence":"first","affiliation":[{"name":"ICGM, University of Montpellier, CNRS, ENSCM, 34293 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8801-7242","authenticated-orcid":false,"given":"Claudia","family":"Cammarano","sequence":"additional","affiliation":[{"name":"ICGM, University of Montpellier, CNRS, ENSCM, 34293 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olinda","family":"Gimello","sequence":"additional","affiliation":[{"name":"ICGM, University of Montpellier, CNRS, ENSCM, 34293 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2076-058X","authenticated-orcid":false,"given":"Anne","family":"Galarneau","sequence":"additional","affiliation":[{"name":"ICGM, University of Montpellier, CNRS, ENSCM, 34293 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2652-5174","authenticated-orcid":false,"given":"Vasile","family":"Hulea","sequence":"additional","affiliation":[{"name":"ICGM, University of Montpellier, CNRS, ENSCM, 34293 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1131","DOI":"10.1007\/s11244-009-9271-8","article-title":"Impact of Zeolites on the Petroleum and Petrochemical Industry","volume":"52","author":"Vermeiren","year":"2009","journal-title":"Top Catal."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1558","DOI":"10.1016\/j.ccr.2011.03.014","article-title":"Inorganic molecular sieves: Preparation, modification and industrial application in catalytic processes","volume":"255","author":"Martinez","year":"2011","journal-title":"Coord.
