The mesopore volume of MYZ was six times higher than that of YZ. [Fe(terpy)2]2+ complexes encapsulated into MYZ and YZ with different Fe contents (Fe(X)L-MYZ and Fe(X)L-YZ; X is the amount of Fe) were prepared and characterized. The oxidation of benzene with H2O2 using Fe(X)L-MYZ and Fe(X)L-YZ catalysts was carried out; phenol was selectively produced with all Fe-containing zeolite catalysts. As a result, the oxidation activity of benzene increased with increasing iron complex content in the Fe(X)L-MYZ and Fe(X)L-YZ catalysts. The oxidation activity of benzene using Fe(X)L-MYZ catalyst was higher than that using Fe(X)L-YZ. Furthermore, adding mesopores increased the catalytic activity of the iron complex as the iron complex content increased.<\/jats:p>","DOI":"10.3390\/molecules27206852","type":"journal-article","created":{"date-parts":[[2022,10,13]],"date-time":"2022-10-13T22:21:11Z","timestamp":1665699671000},"page":"6852","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Direct Hydroxylation of Benzene with Hydrogen Peroxide Using Fe Complexes Encapsulated into Mesoporous Y-Type Zeolite"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6669-3597","authenticated-orcid":false,"given":"Syuhei","family":"Yamaguchi","sequence":"first","affiliation":[{"name":"Department of Materials Science and Biotechnology, Graduate School of Science and Engineering, Ehime University, 3 Bunkyo-cho, Matsuyama 791-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuito","family":"Ishida","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Biotechnology, Graduate School of Science and Engineering, Ehime University, 3 Bunkyo-cho, Matsuyama 791-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hitomu","family":"Koga","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Biotechnology, Graduate School of Science and Engineering, Ehime University, 3 Bunkyo-cho, Matsuyama 791-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidenori","family":"Yahiro","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Biotechnology, Graduate School of Science and Engineering, Ehime University, 3 Bunkyo-cho, Matsuyama 791-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2879","DOI":"10.1021\/cr9411886","article-title":"Activation of C-H Bonds by Metal Complexes","volume":"97","author":"Shilov","year":"1997","journal-title":"Chem.
