Polyoxometalate-based frameworks for photocatalysis and photothermal catalysis

Abstract

Polyoxometalate-based frameworks (POM-based frameworks) are extended structures assembled from metal-oxide clusters units and organic frameworks that simultaneously possess the virtues of POMs and frameworks. They have been attracting immense attention...

Highly efficient degradation of polyesters and polyethers by decatungstate photocatalysis

“…Polyoxometalates (POMs) have emerged as compelling materials for efficient photocatalysts. 8,9 POMs are structurally well-defined nanometre-sized metal–oxide clusters with diverse structures. The redox potentials, acid–base properties, and electronic structures of POMs can be precisely controlled at the molecular level.…”

An iron-containing POM-based hybrid compound as a heterogeneous catalyst for one-step hydroxylation of benzene to phenol

“…Polyoxometalates (POMs), as a class of inorganic metal oxide clusters with a rich structure and excellent redox properties, have attracted broad attention in the fields of catalysis, optics, magnetism, etc . 20–32 Among numerous POM-based materials, molybdovanadophosphoric acid (PMoV) with the Keggin structure has attracted the attention of a wide range of researchers. Since this form of polyacid has abundant and variable metal valence states, it can activate molecular oxidation to obtain reactive oxygen species and easily selectively oxidize reactive organic substrates without the addition of reducing agents.…”

Donor–Acceptor Assembly of Amphiphilic Molecules Based on 9,10-Distyrylanthracene Derivatives with Terminal Naphthalene Groups

“…The development of charge transfer (CT) composite soft materials has always been a concern for researchers, such as liquid crystals , and supramolecular networks. , Donor (D)–acceptor (A) interaction is one of the important noncovalent interactions widely used in the construction of charge transfer complexes. − A novel CT material has been successfully developed in aqueous solutions based on supramolecular self-assembly between different electron donors and electron acceptors. These materials are composed of hierarchical self-assembly through micelles, nanospheres, nanotubes, or fibers .…”
