Synthesis of nanostructured marcasite FeS2 for energy storage applications.

The synthesis of marcasite FeS2 is of great interest as this area is seldom studied due to its sophisticated synthesis methods. In fulfillment of growing energy demands, there is need of cost effective alternates for energy storage devices. Nanostructured marcasite iron disulfide (FeS2) is a promising candidate as anode material for energy storage devices. FeS2 exist in many phases out of which marcasite and pyrite are best suitable for energy storage applications. Purity of the phase is a big challenge for its application oriented use. Pure marcasite (FeS2) has been synthesized by low cost, environmentally friendly hydrothermal route. The synthesized material has been characterized by X-ray Diffraction (XRD). Cyclic voltammetry results show the significant electrochemical performance of marcasite. This work purposes a vision to develop marcasite based electrode material for energy storage devices.
