Transition metal sulfides are widely used in supercapacitor electrode materials and exhibit excellent performance because of their rich variety, low price, high theoretical specific capacity. At present, the main methods to prepare transition include hydrothermal method electrochemical method. In order further improve performance, two aspects can be addressed. Firstly, by controllable synthesis nanomaterials, porous structures large surface areas achieved, thereby improving ion transport efficiency. Secondly, combining with other energy storage materials, such as carbon oxides, synergy between different fully utilized. However, future research still needs address some challenges. guide in-depth research, it is necessary combine current research-derived knowledge propose a direction for development sulfide materials.

Abstract Future energy storage and conversion devices will benefit from the development of active electrode materials that serve as both an electrocatalysts device. Recently, mixed metal sulfides are cheaper have improved electrical electrochemical performance than their oxide/hydroxide similarly has garnered a lot interest for use in electro catalysis applications. In this, sulfides, zinc manganese cobalt sulfide (ZMCS) reduced graphene oxide composite (rZMCS) were successfully synthesized via hydrothermal route overall water splitting supercapacitor. The prepared characterized through x-ray diffraction, photoelectron spectroscopy, Field emission scanning electron microscope, transmission microscope with elemental mapping Brunauer–Emmett–Teller analysis.
