Array configurations of oxometallate–Ag cluster hybrid nanocomposites

Abstract

Oxometallate (MO)-modified Ag clusters have attracted considerable research interest due to their aesthetic structures and fascinating properties. MOs can be a key factor in the organization of Ag ions into a complex entity in an ordered way. Enormous effort has been devoted to exploiting the synthetic strategy of MO–Ag cluster hybrid nanocomposites. Herein, we intend to review the recent progress in the design and construction of MO–Ag clusters with daedal architectures and potential applications. Accordingly, six different types of MO–Ag clusters are summarized mainly in terms of array configurations: (1) MOs @ Ag shells; (2) Ag core @ MOs; (3) Ag core @ MOs @Ag shells; (4) coordination polymers; (5) intercluster compounds and (6) mixed array configurations. Besides, the synergistic effects between MOs and Ag clusters are presented. Based on the current development in this area, this minireview is expected to provide a perspective on controllable preparation of MO–Ag clusters, and a basic understanding of the structure/property correlations of Ag nanoparticle-metal oxide materials, thereby assisting in building functional nanomaterials.
