These composites were based on porous metal\u2013organic frameworks (MOFs), specifically the zinc-based ZIF-8, activated catalytically by the incorporation of Keggin-type phosphomolybdic acid (PMo\n                    <jats:sub>12<\/jats:sub>\n                    ).

Both materials were characterized by FTIR-ATR, PXRD, SEM, EDS, and ICP-OES. The catalytic performance evaluation revealed that both composites exhibited high conversion rates under a sustainable solvent-free system (98% of conversion was achieved after 24\u00a0h), and high selectivity toward 2-Amino-1,2-diphenylethanol, along with notable robustness and recyclability.\n                  <\/jats:p>","DOI":"10.3389\/fchem.2026.1894924","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T05:34:07Z","timestamp":1789623247000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Active porous ZIF-8 based hybrid catalysts for solvent-free reactions"],"prefix":"10.3389","volume":"14","author":[{"given":"C\u00e9sar D.","family":"Sampaio","sequence":"first","affiliation":[{"name":"LAQV \/ REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences - University of Porto","place":["Porto, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu\u00eds","family":"Dias","sequence":"additional","affiliation":[{"name":"LAQV \/ REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences - University of Porto","place":["Porto, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabel","family":"Santos-Vieira","sequence":"additional","affiliation":[{"name":"CICECO \u2013 Aveiro Institute of Materials, Department of Chemistry, University of Aveiro","place":["Aveiro, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eul\u00e1lia","family":"Pereira","sequence":"additional","affiliation":[{"name":"LAQV \/ REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences - University of Porto","place":["Porto, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu\u00eds","family":"Cunha-Silva","sequence":"additional","affiliation":[{"name":"LAQV \/ REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences - University of Porto","place":["Porto, Portugal"]},{"name":"LNEG - Laborat\u00f3rio Nacional de Energia e Geologia IP","place":["Lisboa, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F\u00e1tima","family":"Mirante","sequence":"additional","affiliation":[{"name":"LAQV \/ REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences - University of Porto","place":["Porto, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salete S.","family":"Balula","sequence":"additional","affiliation":[{"name":"LAQV \/ REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences - University of Porto","place":["Porto, Portugal"]},{"name":"LAQV \/ REQUIMTE, Department of Chemistry, Nova School of Science and Technology, Nova University of Lisbon","place":["Monte daCaparica, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,17]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"17844","DOI":"10.1039\/d2dt02976f","article-title":"Unveiling the structural transformations of the PW11Co@ZIF-67 nanocomposite induced by thermal treatment","volume":"51","author":"Abdelkader-Fern\u00e1ndez","year":"2022","journal-title":"Dalton Trans."},{"key":"B2","doi-asserted-by":"publisher","first-page":"3355","DOI":"10.1039\/d4na00142g","article-title":"Zeolitic imidazolate framework-8 encapsulated with Mo-based polyoxometalates as surfaces with antibacterial activity against Escherichia coli","volume":"6","author":"Abdelkhalek","year":"2024","journal-title":"Nanoscale Adv."},{"key":"B3","doi-asserted-by":"publisher","first-page":"14690","DOI":"10.1039\/d0dt02949a","article-title":"Metal organic frameworks decorated with free carboxylic acid groups: topology, metal capture and dye adsorption properties","volume":"49","author":"Ahamad","year":"2020","journal-title":"Dalton Trans."},{"key":"B4","doi-asserted-by":"publisher","first-page":"213023","DOI":"10.1016\/j.ccr.2019.213023","article-title":"Linker functionalized metal-organic frameworks","volume":"399","author":"Ali Akbar Razavi","year":"2019","journal-title":"Coord.
