abstract	Tungsten sulfide (WS<sub<2</sub<) and tungsten carbide (W<sub<2</sub<C) are materialized as the auspicious candidates for various electrochemical applications, owing to their plentiful active edge sites and better conductivity. In this work, the integration of W<sub<2</sub<C and WS<sub<2</sub< was performed by using a simple chemical reaction to form W<sub<2</sub<C/WS<sub<2</sub< hybrid as a proficient electrode for hydrogen evolution and supercapacitors. For the first time, a W<sub<2</sub<C/WS<sub<2</sub< hybrid was engaged as a supercapacitor electrode and explored an incredible specific capacitance of ~1018 F g<sup<−1</sup< at 1 A g<sup<−1</sup< with the outstanding robustness. Furthermore, the constructed symmetric supercapacitor using W<sub<2</sub<C/WS<sub<2</sub< possessed an energy density of 45.5 Wh kg<sup<−1</sup< at 0.5 kW kg<sup<−1</sup< power density. For hydrogen evolution, the W<sub<2</sub<C/WS<sub<2</sub< hybrid produced the low overpotentials of 133 and 105 mV at 10 mA cm<sup<−2</sup< with the small Tafel slopes of 70 and 84 mV dec<sup<−1</sup< in acidic and alkaline media, respectively, proving their outstanding interfaced electrocatalytic characteristics. The engineered W<sub<2</sub<C/WS<sub<2</sub<-based electrode offered the high-performance for electrochemical energy applications.
