The hierarchical porosity enhanced mass transport and accessibility to active metal sites, improving reaction selectivity and efficiency. Supported metal sulfides served as hydrogenation sites, crucial for aromatic ring activation and coke suppression. By optimizing the synergy between hydrogenation and cracking functions, the optimized Ni1W\/HPY catalyst achieved complete naphthalene conversion with a BTX yield of 92.5%. The spatial distribution of WO3 crystallites facilitated functional separation, promoting selective conversion. These findings underscore the importance of metal\u2013acid balance and pore architecture in designing efficient hydrocracking catalysts.<\/jats:p>","DOI":"10.3390\/molecules30194023","type":"journal-article","created":{"date-parts":[[2025,10,10]],"date-time":"2025-10-10T09:45:01Z","timestamp":1760089501000},"page":"4023","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Optimizing Metal Sites in Hierarchical USY for Selective Hydrocracking of Naphthalene to BTX"],"prefix":"10.3390","volume":"30","author":[{"given":"Kunyi","family":"Zheng","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Linyi University, Linyi 276000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mingjia","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Heavy Oil Processing, China University of Petroleum, Beijing 102249, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-8533-7319","authenticated-orcid":false,"given":"Haidong","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Linyi University, Linyi 276000, China"},{"name":"State Key Laboratory of Heavy Oil Processing, China University of Petroleum, Beijing 102249, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiu","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Linyi University, Linyi 276000, China"},{"name":"State Key Laboratory of Heavy Oil Processing, China University of Petroleum, Beijing 102249, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xilong","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Heavy Oil Processing, China University of Petroleum, Beijing 102249, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"123461","DOI":"10.1016\/j.cej.2019.123461","article-title":"Engineering dual bed hydrocracking catalyst towards enhanced high-octane gasoline generation from light cycle oil","volume":"389","author":"Peng","year":"2020","journal-title":"Chem.
