“…Monometallic MOF can impede the flow of charge carriers, reducing the specific capacitance and overall performance which is a major drawback in supercapacitors. [40,41] With day-by-day advancement in research on MOFs, the discovery of bimetallic [42][43][44] (e.g., NiCo-based) and trimetallic [45][46][47] (e.g., NiCo with transition metals like Fe, Mn, and Mg) MOF variants still faces stability problems with others facing fewer capacitance values. One important parameter that can affect the performance of supercapacitor is the deposition methodology.…”

Owing to the worldwide energy requirements, metal–organic frameworks (MOFs) have been extensively used as electrode material. Ternary MOFs have been of prime importance because of their characteristic of a variety of oxidation states than mono‐ and bimetallic MOFs. Herein, a novel comparison and superiority of binder‐free MOF deposition known as in situ (IN) on the substrate have been investigated over the slurry deposition method involving the excellent properties of ternary MOFs. Confirmation of MOF formation using X‐ray diffraction and investigation of its morphological features have been explored using field‐emission scanning electron microscopy. Energy dispersive X‐ray area mapping has also been integrated for conformity of uniform elemental distribution. The electrochemical properties of NiCoMn‐MOF have been investigated and the results obtained for NiCoMn deposited using IN methodology are superior due to excellent penetration of MOF inside substrate that provides the basis of excellent electrochemical properties. A specific capacitance of 1000 C g−1 at 4 A g−1 in 3‐electrode assembly has been achieved accompanied by energy and power density of 55 Wh kg−1 and 2467 W kg−1 in 2‐electrode setup. An excellent cyclic stability of about 97% has been obtained after subjecting the asymmetric supercapacitor device to 5000 charge/discharge cycles at 20 A g−1. Diffusive nature dominancy over capacitive is also observed by manipulating Dunns’ model. The superior and novel aspect of using IN deposition may pave the way for their efficient use in energy storage devices.

Layered double hydroxides (LDHs), promising bifunctional electrocatalysts for overall water splitting, are hindered by their poor conductivity and sluggish electrochemical reaction kinetics. Herein, a hierarchical Cu‐doped NiCo LDH/NiCo alloy heterostructure with rich oxygen vacancies by electronic modulation is tactfully designed. It extraordinarily effectively drives both the oxygen evolution reaction (151 mV@10 mA cm−2) and the hydrogen evolution reaction (73 mV@10 mA cm−2) in an alkaline medium. As bifunctional electrodes for overall water splitting, a low cell voltage of 1.51 V at 10 mA cm−2 and remarkable long‐term stability for 100 h are achieved. The experimental and theoretical results reveal that Cu doping and NiCo alloy recombination can improve the conductivity and reaction kinetics of NiCo LDH with surface charge redistribution and reduced Gibbs free energy barriers. This work provides a new inspiration for further design and construction of nonprecious metal‐based bifunctional electrocatalysts based on electronic structure modulation strategies.
