The environmental and energy utilization issues are increasing day by day due to overuse of fossil fuels. The need of clean and efficient energy sources are of high demand. Meanwhile the energy density and fast charging and durable energy storage devices are being searched and fabricated. Hydrogen (H₂) produced form water through electrochemical water splitting is considered as the principal renewable and ecofriendly energy source. The electrochemical water splitting via hydrogen evolution reaction (HER) is of great importance and research interest. The commercialization of HER is still a prevailing challenge. The search new catalysts of high efficiency with low cost to replace noble metal catalysts is need of the day. In this category molybdenum carbide (Mo₂C) is one, which shows efficient performance towards HER in both acidic and basic medium. Thus the synthesis of low cost carbon coated Mo₂C at nanoscale is highly desirable. The nature and amount of carbon over Mo₂C enhances the electrochemical characteristics. The waste material utilization for its synthesis will further make the process more economical. In the present study, a new path to synthesize carbon coated Mo­₂C nano powders utilizing carbon wastes as carbon source in specially designed autoclave at low temperature. The environmental issues caused due to disposal of these wastes will be addressed. The HER activity of Mo₂C was studied in acidic medium 0.5M H₂SO₄ via three electrode setup with glassy carbon electrode (GCE), graphite rod and reversible hydrogen electrode (RHE) as working, counter and reference electrodes, respectively. The as synthesized product showed efficient HER results and higher cyclic stability. Moreover, the double layer capacitance (C_dl) characteristics reveal the synthesized material as suitable electrode candidate for storage applications.
