The key to achieve this goal is the parallel oxidation of sulfur and nitrogen compounds present in fuels, which is only achieved by an active and recovered catalyst. A novel heterogeneous catalyst was successfully prepared by the encapsulation of an imidazolium-based polyoxometalate (POM) into a ZIF-8 framework ([BMIM]PMo12@ZIF-8). This composite material revealed exceptional catalytic efficiency to concurrently proceed with the oxidative desulfurization and denitrogenation of a multicomponent model fuel containing various sulfur and nitrogen compounds. A complete removal of all these compounds was achieved after only one hour and the catalyst system was able to be reused for ten consecutive cycles without loss of efficiency. In fact, an ionic liquid POM was incorporated in the ZIF-8 for the first time, and this composite compound was originally applied as a catalyst for simultaneous oxidative desulfurization and denitrogenation processes.<\/jats:p>","DOI":"10.3390\/molecules27051711","type":"journal-article","created":{"date-parts":[[2022,3,6]],"date-time":"2022-03-06T20:40:02Z","timestamp":1646599202000},"page":"1711","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Ionic Liquid-Based Polyoxometalate Incorporated at ZIF-8: A Sustainable Catalyst to Combine Desulfurization and Denitrogenation Processes"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5558-5665","authenticated-orcid":false,"given":"Dinis F.","family":"Silva","sequence":"first","affiliation":[{"name":"LAQV\/REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]},{"given":"Alexandre M.","family":"Viana","sequence":"additional","affiliation":[{"name":"LAQV\/REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8607-4323","authenticated-orcid":false,"given":"Isabel","family":"Santos-Vieira","sequence":"additional","affiliation":[{"name":"CICECO\u2014Aveiro Institute of Materials, Department of Chemistry, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8984-0473","authenticated-orcid":false,"given":"Salete S.","family":"Balula","sequence":"additional","affiliation":[{"name":"LAQV\/REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9229-1412","authenticated-orcid":false,"given":"Lu\u00eds","family":"Cunha-Silva","sequence":"additional","affiliation":[{"name":"LAQV\/REQUIMTE, Department of Chemistry and Biochemistry, Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3339","DOI":"10.1021\/acs.energyfuels.8b03973","article-title":"Evaluation of Operating and Design Parameters of Pressurized Flue Gas Systems with Integrated Removal of NOx and SOx","volume":"33","author":"Ajdari","year":"2019","journal-title":"Energy Fuels"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"177","DOI":"10.1016\/j.jenvman.2018.03.014","article-title":"Numerical modelling of emissions of nitrogen oxides in solid fuel combustion","volume":"215","author":"Besenic","year":"2018","journal-title":"J.
