Application of Polyoxometalate-based composites for sensor systems: A review

Composites based on polyoxometalates (POMs) have been increasingly attracted by many researchers due to their multitudinous architectures and excellent redox activities as well outstanding proton electron transport capacities. Lately, much research has done POMs composited with well-porous framework materials (including ZIFs, MOFs) or conducting polymers, carbon quantum dot (CQD), graphene, structures (e.g. nanotubes (CNTs)), metal nanoparticles (NPs). The results exhibited improved stability enhanced electrochemical performances. Hence, developing POM-based composite (PCMs) long a topic of interest for chemical researchers. Herein, the properties applications pristine POMs, doped composite-based are reviewed in detail. various compositions sensing application such POMs-nanocarbon composites (POMs-graphene POMs-carbon nanotube composites), POMs-conductive polymer composites, POMs-metal also investigated this review.
