Resumen:
Cyclohexylphenol (CHP) is a high added-value chemical, extensively used for the preparation of dyes, resins and biocides. This molecule is currently synthetized by phenol alkylation with cyclohexene/cyclohexanol using highly polluting mineral Bronsted acids as catalysts. The [read more]

Resumen:
Porous Fe carboxylates are amongst the most promising MOF-based materials due to their low price, low toxicity, metal environments (including open metal sites) and remarkable (meso)porosity variety. Fe-MOFs based on the cluster [Fe3O(X)(solvent)(2)](6+), that is, MIL-101(Fe), MIL-100(Fe) and semiamorphous Fe-BTC, are of [read more]

Resumen:
The aim of this study is to obtain Ti-containing Periodic Mesoporous Organosilica (PMO) materials with catalytic activity in epoxidation reactions. Characterization of the PMO materials using X ray diffraction, N-2 sorption isotherms, chemical analysis (ICP-OES) and UV-vis spectroscopy reveals that the Ti-PMO [read more]

Resumen:
The MOFs selected in this work are NH2-MIL-53(Al), MIL-100(Fe) and UiO-66 type (Zr-BDC and NH2-Zr-BDC). We have tried to assist the sustainable synthesis of MOFs, at room temperature and in water as a solvent, with the presence of non-ionic surfactants: [read more]

Resumen:
Zr-based MOFs have stimulated the interest of scientific community due to their exceptional variety in composition, structure and chemical environment as well as their consequent applications including photo catalysis. This work presents the successful preparation of nanosized highly-porous Zr-BDC MOFs under sustainable [read more]
