Highly thermally stable heterogeneous catalysts: study of 0D and 3D porphyrinic MOFs

摘要: Heterogeneous catalysts are greatly preferred for green chemistry in many industrial processes and, the past decade, promising results have been achieved order to improve catalytic activity of metal organic frameworks (MOFs). Accordingly, porphyrins make design new coordination polymers with better properties possible, taking into account important functions they develop nature. In this sense, porphyrin-based MOFs becoming very relevant heterogeneous catalysis. Thus, aim work was obtain metalloporphyrinic exhibiting activity. Studying effect dimensionality on MOF (including thermal stability and activity), work, we study two different dimensionalities, 3D [Ni5(H2TCPP)2O(H2O)4]·nS (1) 0D [Cu(H4TCPP)]·6DMF (2) (where H6TCPP is meso-tetra(4-carboxyphenyl)porphyrin, DMF N,N-dimethylformamide S solvent). The structural features both compounds, combined their high accessible networks, responsible excellent behaviour as catalysts. It worth mentioning that a significant reduction reaction time compared other reported has observed. recyclability one herein studied outstanding. Further characterization carried out by means single crystal X-ray diffraction, IR spectroscopy, thermogravimetry (TG), powder diffraction (XRD) transmission electron microscopy (TEM).
