Depending on the pH and the solvent used, different topologies were obtained (namely, MIL-96, MIL-100 and MIL-110). On the one hand, MIL-110 was obtained at lower tem- peratures than those commonly reported in the literature and without additives to control the pH; on the other hand, MIL-100 with crystallite sizes as small as 30 ± 10 nm could be easily synthesized in a mixture of H2O and EtOH with a H2O/EtOH molar ratio of 3.4 at pH 2.6 in the presence of CTAB. The resulting material displays a hierarchical porosity that combines the microporosity from the MOF and the non- ordered mesopores defined in between the MOF nanoparticles. Interestingly, the maximum of the pore size distribution could be varied between 3 and 33 nm. Finally, at pH 2.5 and using water as a solvent, platelets of MIL-96, a morphology never observed before for this MOF, were synthesized with a (001) preferential crystal orientation, the (001) plane running parallel to the bipyramidal cages of the MIL-96 topology.17 info:eu-repo/grantAgreement/ES/MINECO/MAT2013-40566-R info:eu-repo/grantAgreement/EC/FP7/335746/EU/Crystal Engineering of Metal Organic Frameworks for application in Mixed Matrix Membranes/CRYSTENG-MOF-MMM info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.849 2015 CHEMISTRY, MULTIDISCIPLINARY 37 / 163 = 0.227 2015 Q1 T1 CRYSTALLOGRAPHY 4 / 26 = 0.154 2015 Q1 T1 1.04 2015 Chemistry (miscellaneous) 2015 Q1 Materials Science (miscellaneous) 2015 Q1 Condensed Matter Physics 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dikhtiarenko, Alla (orcid)0000-0002-5229-2717 Mayoral, Alvaro (orcid)0000-0002-4954-1188 Tellez, Carlos Universidad de Zaragoza (orcid)0000-0003-1512-4500 Coronas, Joaquin Universidad de Zaragoza Kapteijn, Freek Gascon, Jorge 5005 555 Universidad de Zaragoza Dpto.
