Abstract An effective way to explore high performance electrode for supercapacitor is developed by employing exfoliated 2D layered MnO2 nanosheet as a hybridization matrix for Prussian blue (PB) material. The hybrid material of PB-layered MnO2 is synthesized by crystal growth of PB nanocrystal on the exfoliated MnO2 nanosheet at room temperature. Electron microscopic and spectroscopic analyses clearly demonstrate the homogeneous hybridization between PB and MnO2 . The obtained PB-layered MnO2 nanohybrid shows expanded surface area than does the pristine PB material, reflecting the usefulness of hybridization with MnO2 nanosheet in increasing the porosity of PB material. Of prime importance is that the PB-MnO2 nanohybrid exhibits larger capacitances with better cyclability than does the MnO2 free-PB material. The present study clearly demonstrates that the hybridization with exfoliated metal oxide nanosheet is quite effective in improving the electrode performance of PB materials.
