A synthetic route for improving the formation of MOFs has been developed and is triggered by hydrogen peroxide (H2O2) to promote the formation of terephthalate-based MOFs of MIL-53 and MIL-68 types, specifically those made from Fe3+ and Al3+ and mixtures of both. Different characterization techniques (TGA, XRD, SEM, TEM, N2 porosimetry and Raman, mass and NMR spectroscopies) gave insights into the effect of H2O2 on the MOF synthesis. The reaction yield was significantly improved (the highest yield being 74 % for MIL-53(Al)), while crystallinity and N2 adsorption properties were mostly maintained for phases based on Al and Al/Fe. Furthermore, a reaction mechanism was envisaged from the mass spectroscopic analysis of the reaction solutions, thus suggesting that H2O2 plays the role of a µ-hydroxo bridge promoter, favoring the link between terephthalate ligands and aluminum-containing species to give rise to the µ-carboxylate bridges, leading to a faster growth of the final MOF, and offering a novel MOF synthesis approach. info:eu-repo/grantAgreement/ES/DGA/E102 info:eu-repo/grantAgreement/ES/DGA/T43-17R info:eu-repo/grantAgreement/EC/FP7/321642/EU/Development of a microfluidic platform to produce nanomaterials and assessment on new nanotechnology applications/PLATFORM2NANO info:eu-repo/grantAgreement/ES/ISCIII/CIBER-BBN info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2016-77290-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.863 2020 CHEMISTRY, MULTIDISCIPLINARY 95 / 178 = 0.534 2020 Q3 T2 0.801 2020 Chemistry (miscellaneous) 2020 Q1 info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/acceptedVersion Jiménez-Fernández, Isabel López-Ram-de-Viu, Pilar Universidad de Zaragoza (orcid)0000-0001-8105-2432 Sebastian, Víctor Universidad de Zaragoza (orcid)0000-0002-6873-5244 Coronas, Joaquín Universidad de Zaragoza (orcid)0000-0003-1512-4500 5005 555 Universidad de Zaragoza Dpto.
