Hybrid supercapacitors (HSCs) are devices that have energy storage characteristic of batteries and rapid charging properties of supercapacitors (SCs). HSCs have attracted considerable interest as promising solutions for advanced energy storage applications. Metal-organic frameworks (MOFs) offers high surface area, adjustable porosity, improved accessibility of ions and dispersing active material effectively. While, MoTe2 have its excellent electrical conductivity and catalysis efficiency and can improve charge storage and transport characteristics of MOFs by incorporation. In this study, a resilient and self-supporting electrode of Fe-MOF@MoTe2 composite was developed by a hydrothermal technique. In electrochemical behaviors, Fe-MOF@MoTe2 composite achieved quite excellent specific capacity 1392 C/g at current density of 1.0 A/g. Within HSC configuration, the electrode achieved a specific energy of 80.3 Wh/kg and a marvelous specific power of 800 W/kg. As an electrocatalyst for hydrogen evolution reaction (HER), it demonstrated striking low overpotential value at 130.4 mV along with good slope of Tafel plot of 106.3 mV/dec. Such findings emphasize prospects of Fe-MOF@MoTe2 as an advanced electrode material, well-suited for efficient energy retention and electrocatalytic applications.
