Achieving ultra-trace analysis and multi-light driven photodegradation toward phenolic derivatives via a bifunctional catalyst derived from a Cu(i)-complex-modified polyoxometalate

Abstract

In the field of water decontamination, the design of a new catalyst for sensitive detection and effective removal of toxic phenolic compounds are important and challenging. Herein, a new bifunctional...

Engineering the heterogeneous photocatalytic activity of crystalline decatungstate-based coordination polymers

“…For compound 3 , a broad absorption peak at 408 nm and a shoulder peak around 550 nm are observed. Though Cu( i ) compounds are typically colorless due to their d 10 configuration, compound 3 shows a dark red color which is likely to be arisen from charge transfer transitions from the Cu( i ) centre to decatungstate 31,32 and 4,4′-bipy ligands. 33…”

Crystalline nanosheets of three-dimensional supramolecular frameworks with uniform thickness and high stability

“…Organic molecule-based frameworks including supramolecular frameworks (SMFs), 1,2 metal–organic frameworks (MOFs), 3,4 and covalent organic frameworks (COFs) 5–8 have exhibited great application potentials in various areas such as gas storage and separation, 9–15 catalysis, 16–20 sensing, 21–24 enzyme encapsulation, 25,26 and proton conduction 27,28 due to their periodic porous structure and functional diversity. Crystalline materials with ultrathin nanosheet morphology have aroused significant research interest in the past two decades since the report of graphene in 2004.…”

Four Chromic Compounds Constructed from Keggin Polyoxometalates and Viologens with Applications in Ultraviolet, Metal Ion Detection, and Ink-Free Printing

“…Polyoxometalate (POM) is an important branch of the inorganic field, which is a kind of metal oxygen clusters formed by oxygen connection of pretransition metal ions. − Until now, POM has been widely studied as a functional component and applied in many fields such as light, electricity, and magnetism. − Moreover, the surface of POMs is rich in electrons, which can provide electrons easily. Thus, POMs own excellent redox properties, inducing the applications in electrochemistry and catalysis. − Furthermore, the characteristics of rich electrons of POMs can conduce electron transition, which makes POMs act as precursors of chromic materials .…”
