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]

Semiamorphous Fe-BDC: The missing link between the highly-demanded iron carboxylate MOF catalysts

Doi: 10.1016/j.cattod.2021.11.004.

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]

Synthesis of cyclohexylphenol via phenol hydroalkylation using Co2P/zeolite catalysts
