2019-12-11 Herein, by means of microwave-assisted synthetic approach, a soluble porphyrinic MOF, denoted as S-Al-PMOF, has been successfully fabricated. In contrast to the Bulk-Al-PMOF synthesized by the conventional hydrothermal route, which requires 180℃ and 16 h, the S-Al-PMOF obtained by the microwave-assisted method is very efficient and takes 30 min only at 140℃. 2020-01-10 Therefore, they investigated several porphyrin‐based MOFs (namely PCN‐221, PCN‐222, PCN‐223, PCN‐224, MOF‐525 and Al‐PMOF) only differing in their topology and thus in the spatial arrangement of the active sites. Noteworthy, the activity of this reaction linearly … structure of Al-PMOF as a function of the metal M substituted in the porphyrin centre (M=Fe, Co, Ni, Cu, Zn). We found that the energy levels of the frontier orbitals in these materials are in the correct positions for solar fuel synthesis photocatalysis, although the band gaps obtained were still a bit too wide for The tunable chemistry linked to the organic/inorganic components in colloidal nanocrystals (NCs) and metal–organic frameworks (MOFs) offers a rich playground to advance the fundamental understanding of materials design for various applications. Herein, we combine these two classes of materials by synthesizing NC/MOF hybrids comprising Ag NCs that In the case of Al-PMOF, the organic linker TCPP (TCPP = meso-Tetra(4-carboxyphenyl)porphyrin) produces H2 upon visible light illumination, where the electron from TCPP cannot migrate to the SBUs comprised of Al-oxo chains owing to their higher energy levels.

Abstract: The use of photosensitizers as organic ligands in Metal-Organic Frameworks (MOFs) is a common practice to engineer A photocatalyst consisting of a porphyrin-based metal–organic framework (Al/PMOF) and amine-functionalized graphene (NH2-rGO) has been designed to reduce CO2. The structure of the hybrid MOF is investigated as a function of weight percentage of NH2-rGO added to the Al-PMOF.
