The rise in need has led to the requirement of advanced smart materials to conquer the present and future disasters in energy storage and generation. Among various materials, metal organic framework (MOF) has been chosen as an active material with tunable structures, porous inorganic− organic structure, and flexibility, which allows it to play a vital role in synthesizing highly efficient energy material. In recent years, MOF materials have voiced remarkable energy storage efficiency and conversion by encouraging most of the challenges that are typically faced by transition metals, metal hydroxides, etc. Among various supercapacitor materials, nickel is a new class of electrode with excellent capacitance. To overcome some limitations, such as cyclic stability and low conductivity, researchers are working on tuning its structure and morphology. In this work, Ni-MOFs are synthesized by varying the solvent ratio using the hydrothermal method. The prepared N-0.5 MOF electrode material delivers a high specific capacity of 1004.67 C g −1 at 1 A g −1 current density. Furthermore, the hybrid supercapacitor device is fabricated using N-0.5 as the anode and activated carbon (AC) as the cathode, and its electrochemical performances are investigated in both the gel and aqueous electrolytes. All the results affirm that the prepared electrode material shows better electrochemical performance and serves as a suitable supercapacitor electrode.

“…Hence, many efforts have been made to develop alternative materials with HER and OER activity, which are abundant and inexpensive on Earth. They have been used to design economically feasible catalysts, including oxides, 11,12 sulfides, 13,14 selenides, 15,16 nitrides, 17,18 carbides, 19,20 and phosphates, 21,22 with remarkable progress. Despite designing economically feasible catalysts, the actual performance of these alternative catalysts must be improved with respect to those of precious metal catalysts.…”
