Protection of Ag Clusters by Metal‐Oxo Modules

Abstract

Accordingly, three different types of clusters are summarized:(1) Ag clusters protected by mononuclear oxometallates; (2) Ag clusters protected by block-like metal-oxo clusters; (3) Ag clusters protected by hollow-like metal-oxo clusters. The aim of this concept is to offer possible general guidance and insight into future rational design of more metal-oxo clusters protected silver clusters or even other coinage metal nanoclusters.

Variable control of the electronic states of a silver nanocluster via protonation/deprotonation of polyoxometalate ligands

“…11 Therefore, POMs can be fascinating components to design molecular hybrids with organic molecules and metal nanoclusters that exhibit unique properties and applications. 12,13 In particular, lacunary POMs can act as inorganic multidentate ligands with abundant reactive oxygen atoms. 14 We recently developed synthetic methods for atomically precise Ag nanoclusters ( e.g.…”

“…), the chemical properties (magnetism, 6,73,83 optics, 75 catalysis, 1,13 biology, 84 etc.) of these metal clusters and the types of shell ligands (thiolate, 85 phosphine, [86][87][88] alkynyl, 89,90 carbonyl, 22 nitrogen 91 /oxygen 92 donor ligands, etc. ), with few summarizing their structural features.…”

Array configurations of oxometallate–Ag cluster hybrid nanocomposites

“…Plenty of MO-Ag cluster hybrid composites have been extensively designed with novel physical/chemical properties and potential applications in the fields of optics, electricity, catalysis, etc. [8][9][10] There are several unique advantages of MO-Ag cluster hybrid composites (Scheme 1):…”

“…9 Moreover, Zhang and his co-workers published a review focusing on Ag clusters protected by oxometallates. 10 These reviews reveal that the arrangements of nanosized silver clusters and MO anions in the crystal structure can account for their synergistic effects. However, there is no comprehensive review summarizing the arrangements of structural configurations in various Ag-MO systems.…”

“…Plenty of MO–Ag cluster hybrid composites have been extensively designed with novel physical/chemical properties and potential applications in the fields of optics, electricity, catalysis, etc . 8–10 There are several unique advantages of MO–Ag cluster hybrid composites (Scheme 1): (1) novel and various coordination motifs between MOs and Ag atoms can enrich the structural diversity of hybrid clusters; (2) MOs can participate in the frontier orbitals of Ag clusters and contribute to the electronic structure, endowing them with unique functionalities; (3) Ag cluster–MO hybrid composites serve as a molecular model for silver nanoparticle/metal oxide materials to advance the fundamental study in nanoscience and nanotechnology. However, one question always made researchers confused as to what specific role do MOs play in the construction of hybrid nanocomposites.…”
