Encapsulation of Metal Clusters within Porous Organic Materials: From Synthesis to Catalysis Applications

Chemistry - An Asian Journal, Journal Year: 2021, Volume and Issue: 17(4)

Published: Dec. 29, 2021

Metal clusters (MCs) with dimensions between a single metal atom and nanoparticles of >2 nm usually possess distinct geometric electronic structures, their outstanding performance in catalysis applications have underpinned broad research interest. However, smaller-sized MCs are easily deactivated by migration coalescence during the process because high surface energy. Therefore, search an appropriate stabilizer for is urgently demanded. In recent years, porous organic polymers (POPs) molecular cages (OMCs), as emerging functional materials, attracted significant attention. Benefiting from spatial confinement, encapsulating into these materials promising approach to guarantee uniform size distribution stability. this review, we aim provide comprehensive summary progress synthetic strategies encapsulated MCs, seek uncover ideas that can stimulate future developments at both fundamental applied levels.
