Recent Advances in Hybrid Materials of Metal Nanoparticles and Polyoxometalates

Abstract

Polyoxometalates (POMs), anionic metal‐oxygen nanoclusters that possess various composition‐dependent properties, are widely used to modify the existing properties of metal nanoparticles and to endow them with new ones. Herein, we present an overview of recent advances in hybrid materials that consist of metal nanoparticles and POMs. Following a brief introduction on the inception of this area and its development, representative properties and applications of these materials in various fields such as electrochemistry, photochemistry, and catalysis are introduced. We discuss how the combination of two classic inorganic materials facilitates cooperative and synergistic behavior, and we also give personal perspectives on the future development of this field.

A Polyoxometalate‐Based Pathologically Activated Assay for Efficient Bioorthogonal Catalytic Selective Therapy

“…Specially, there was the electronic interaction between POM and Cu, which manifested as reversible electron transfer. [2,4,[7][8][9] Besides, we also wanted to know whether the change of pH of the reaction medium would affect the catalytic effect. As shown in Figure 2F and G, the changes of pH had nearly no significant effect on the efficiency of CuAAC reaction catalyzed by Cu-POM, implying that the formation of aggregates did not affect the catalytic activity.…”

“…The excellent catalytic effect of Cu‐POM might result from that POM acted as electron reservoir for modulating the surrounding electronic environment of the catalytic Cu site. Specially, there was the electronic interaction between POM and Cu, which manifested as reversible electron transfer [2, 4, 7–9] . Besides, we also wanted to know whether the change of pH of the reaction medium would affect the catalytic effect.…”

Antioxidative 0-dimensional nanodrugs overcome obstacles in AKI antioxidant therapy

“…POMs are a class of metal-oxygen cluster compounds based on the formation of high-valent early transition metals linked by oxygen. 67 They are ideal models for exploring metal-based antioxidative enzymes due to their ordered framework structure and chemical tunability, as well as their unique properties (hydrophilicity, redox activity, photoactivity, etc.). 68 For example, our group previously designed ultrasmall tungsten (W)-based POM nanodots (TWNDs) with high antioxidant activity for the treatment of AKI (Fig.…”

Molecular nanoarchitectonics: unification of nanotechnology and molecular/materials science

“…The development of functional materials is an important key to solving various problems in human society. Functional materials have been created together with developments of well-established science such as organic chemistry [4][5][6], inorganic chemistry [7][8][9], polymer chemistry [10][11][12], supramolecular chemistry [13][14][15], coordination chemistry [16][17][18], other materials chemistry [19][20][21], and bio-related chemistry [22][23][24]. Accordingly, it has become clear that precise control of structures is necessary to improve functionality [25,26].…”
