Among them, silica hybrid xerogels have emerged as promising candidates due to their simple preparation and tunability: when they are synthesised, depending on the organic precursor and its concentration, their properties can be modulated, and thus, it is possible to prepare materials with \u00e0 la carte porosity and surface chemistry. This research aims to design two new series of silica hybrid xerogels by co-condensation of tetraethoxysilane (TEOS) with triethoxy(p-tolyl)silane (MPhTEOS) or 1,4-bis(triethoxysilyl)benzene (Ph(TEOS)2 and to determine their chemical and textural properties based on a variety of characterisation techniques (FT-IR, 29Si NMR, X-ray diffraction and N2, CO2 and water vapour adsorption, among others). The information gathered from these techniques reveals that depending on the organic precursor and its molar percentage, materials with different porosity, hydrophilicity and local order are obtained, evidencing the easy modulation of their properties. The ultimate goal of this study is to prepare materials suitable for a variety of applications, such as adsorbents for pollutants, catalysts, films for solar cells or coatings for optic fibre sensors.<\/jats:p>","DOI":"10.3390\/gels9050382","type":"journal-article","created":{"date-parts":[[2023,5,8]],"date-time":"2023-05-08T02:29:22Z","timestamp":1683512962000},"page":"382","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Tunability of Hybrid Silica Xerogels: Surface Chemistry and Porous Texture Based on the Aromatic Precursor"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2440-562X","authenticated-orcid":false,"given":"Beatriz","family":"Rosales-Reina","sequence":"first","affiliation":[{"name":"Department of Science, Institute for Advanced Materials and Mathematics (INAMAT2), Public University of Navarre (UPNA), Campus Arrosad\u00eda, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8317-7239","authenticated-orcid":false,"given":"Guillermo","family":"Cruz-Quesada","sequence":"additional","affiliation":[{"name":"Department of Science, Institute for Advanced Materials and Mathematics (INAMAT2), Public University of Navarre (UPNA), Campus Arrosad\u00eda, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nataly","family":"Padilla-Postigo","sequence":"additional","affiliation":[{"name":"IES Plaza de la Cruz, Calle de San Ferm\u00edn, 51, 31003 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marian","family":"Irigoyen-Razquin","sequence":"additional","affiliation":[{"name":"IES Plaza de la Cruz, Calle de San Ferm\u00edn, 51, 31003 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ester","family":"Alonso-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"IES Plaza de la Cruz, Calle de San Ferm\u00edn, 51, 31003 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8849-6298","authenticated-orcid":false,"given":"Mar\u00eda Victoria","family":"L\u00f3pez-Ram\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Organic Chemistry, Faculty of Experimental Sciences, University of Jaen, 23071 Jaen, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0227-9458","authenticated-orcid":false,"given":"Maialen","family":"Espinal-Viguri","sequence":"additional","affiliation":[{"name":"Department of Science, Institute for Advanced Materials and Mathematics (INAMAT2), Public University of Navarre (UPNA), Campus Arrosad\u00eda, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3366-9726","authenticated-orcid":false,"given":"Juli\u00e1n J.","family":"Garrido","sequence":"additional","affiliation":[{"name":"Department of Science, Institute for Advanced Materials and Mathematics (INAMAT2), Public University of Navarre (UPNA), Campus Arrosad\u00eda, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ashok Kumar, S., Shankar, J.S., Gouthaman, S., and Periyasamy, B.K.
