Stable Metal-Organic Framework Based Electrode For Electrochemical Applications

By electrodepositing a layer of Prussian blue (PB) on indium-tin-oxide substrate, followed by subsequent polyaniline (P ANI) deposition, a bilayer P ANI/PB electrode with high charge density (~10 mC/ cm2) can be retained after 60 charging/discharging cycles. Compared with standalone PB electrode, the improvement in electrochemical properties and good morphological control were demonstrated based on P ANI/PB electrode by using cyclic voltammetry and microscopic images respectively. This work paves a promising approach to prepare stable PB-based electrode for electrochemical devices.
