Synthesis and characterization of ultrathin metal coordination Prussian blue nanoribbons

Ultrathin metal coordination Prussian blue (PB) nanoribbons with tunable width have been successfully synthesized. The morphology and microstructure of PB nanoribbons are characterized using UV-vis, FT-IR, AFM, TEM and XRD. PB nanoribbons synthesized possess an ultrathin thickness of approximately 1 nm and narrow width. The width of PB ribbons can be tuned by varying the chain length of polymeric precursors. The PB hybrid nanoribbons synthesized exhibit enhanced thermal stability and electrochemical activity. The merit of narrow and tunable width as well as ultrathin thickness of PB hybrid nanoribbons along with enhanced thermal stability and electrochemical activity makes them potentially useful in nano-devices, biosensors and so on.
