The water oxidation in alkaline media is a kinetically sluggish process and it requires an active electrocatalyst for overall water splitting which is a challenging task to date. Herein, we formulate a platform for the design of efficient NiCo 2 S 4/C nanocomposite using earth abundant and nonprecious materials. The nanocomposites are prepared by scale up hydrothermal method using different carbon contents from acid dehydrated sucrose. They are structurally and morphologically characterized by various analytic techniques. The scanning electron microscopy has shown few microns flower-like morphology of nanocomposite and hexagonal crystalline phase is identified by X-ray diffraction (XRD). Further, high-resolution transmission electron microscopy supported the XRD results, and C, Ni, Co and O elements were found in the composition nanocomposite as investigated by energy-dispersive spectroscopy.
