Coordinative integration of a metal-porphyrinic framework and TiO₂nanoparticles for the formation of composite photocatalysts with enhanced visible-light-driven photocatalytic activities

Abstract

A porphyrinic metal-organic framework (porph-MOF)-based composite photocatalyst with enhanced visible-light-driven photocatalytic performance is successfully constructed involving a bridging linker 4-PySH and TiO2nanoparticles.

A Spiderweb‐Like Metal–Organic Framework Multifunctional Foam

“…After immobilizing ZIF‐8, new peaks were observed in the foam at 396.6 eV in the N 1s spectra, and 160.9 eV and 164.7 eV in the S 2p spectra. This suggested the strong interactions of the amine electron pair (from CNF‐BSA) and sulfur sites (from BSA) with the accessible Lewis acid sites of the MOFs . Furthermore, the peaks at 1021.3 eV and 1044.5 eV, corresponding to the 2p3/2 and 2p1/2 core levels of divalent Zn ions, shifted to 1020 eV and 1043.5 eV, respectively.…”

Metal oxide integrated metal organic frameworks (MO@MOF): rational design, fabrication strategy, characterization and emerging photocatalytic applications

“…1b. 51 The charge transfer between the TiO 2 NPs and PCN-222 matrix enhanced the electron-hole separation in the composite. A morphological study of the composite revealed that the composite maintains the rod shape of the parent MOF and the TiO 2 NPs are uniformly anchored to its surface, which is a typical case of an MO anchored on a pre-synthesized MOF template.…”
