“…Generally, to enhance the storage performance of VN, strategies such as nanostructuring [ 18 , 19 , 20 , 21 ] and hybridization [ 22 , 23 , 24 ] have been employed. The hybridization approach involves carbon-based hybrids [ 21 , 25 , 26 ] and carbon-free hybrids [ 27 , 28 ]. For the VN-carbon-based hybrids electrodes, tremendous advancement has been realized [ 29 , 30 , 31 ], whereas carbon-free VN-based hybrids are still at their starting stage [ 32 , 33 ].…”

Vanadium nitride (VN) shows promising electrochemical properties as an energy storage devices electrode, specifically in supercapacitors. However, the pseudocapacitive charge storage in aqueous electrolytes shows mediocre performance. Herein, we judiciously demonstrate an impressive pseudocapacitor performance by hybridizing VN nanowires with pseudocapacitive 2D-layered MoS2 nanosheets. Arising from the interfacial engineering and pseudocapacitive synergistic effect between the VN and MoS2, the areal capacitance of VN/MoS2 hybrid reaches 3187.30 mF cm−2, which is sevenfold higher than the pristine VN (447.28 mF cm−2) at a current density of 2.0 mA cm−2. In addition, an asymmetric pseudocapacitor assembled based on VN/MoS2 anode and TiN coated with MnO2 (TiN/MnO2) cathode achieves a remarkable volumetric capacitance of 4.52 F cm−3 and energy density of 2.24 mWh cm−3 at a current density of 6.0 mA cm−2. This work opens a new opportunity for the development of high-performance electrodes in unfavorable electrolytes towards designing high areal-capacitance electrode materials for supercapacitors and beyond.

“…It was reported that the Mo 2 N nanobelts, which are porous, showed a high specific capacitance of 160 F/g, high rate capability, and good cyclic stability even at high scanning rates of 100 mVs −1 as a supercapacitor electrode material. Achour et al (2017) reported that a titanium vanadium nitride (TiVN) electrode can be used as an electrode material for microsupercapacitors. A TiVN electrode exhibited an areal capacitance value of 15 mF cm −2 at 2 mVs −1 with extraordinary capacitance retention of more than 99% after 10,000 cycles.…”

Nanosized metal nitrides, due to their chemical characteristics which make them sustainable alternatives to noble metals in catalysis, have drawn the attention of researchers worldwide. Transition metal nitrides are very similar in their method of synthesis, properties, and applications. Their synthetic parameters are considered to be the main factor for determining the effectiveness of metal nitrides in photocatalysis, energy storage devices, remediation of environmental pollutants, gas sensors, and biomedical applications. This review focuses on very recent advances made in synthetic approaches and electrocatalytic applications of metal nitrides. The synthetic approaches will provide an overview of cost of production and consumption of energy and time required for synthesis. Furthermore, some recent techniques that offer new paths for researchers, such as electrochemical, sol-gel, solvothermal, sonochemical, solid-state reaction, chemical synthesis, and many more, are also discussed. Various applications in electrocatalysis, water splitting, lithium ion batteries, and super-capacitors, etc. are summarized. We are confident that this review will provide very useful information for the upcoming community of researchers interested in synthesizing nitrides for various applications.

“…Lithium-ion batteries (LIBs) have become a topic of international research due to their long cycling lifetime, high working voltage, high energy density, high rate capability, and environment-friendliness [4,5]. It could be an important complement for the insufficient of the other power sources, for instance, supercapacitors and fuel cells [6,7,8]. However, commercial graphite is hard to adapt to the demand of widely application duo to the slow Li + diffusion rate and the formation of solid electrolyte interface (SEI) [9].…”

In this work, a series of two-dimensional (2D) large-size nanosheets were prepared through one-step exfoliation of the huge K4Nb6O17 crystals. The K4Nb6O17 nanosheets with the thickness of about 2 nm was used as the templates of dopamine polymerization and was then carbonized to form C-doped K4Nb6O17 nanosheets. More importantly, the C-doped K4Nb6O17 nanosheets exhibited excellent electrochemical performance with high specific capacity (381 mA h g−1 at 0.05 A g−1, 0.5–3.0 V vs. Li/Li+) and stable cyclability at high current density (remarkably, preserved a capacity of discharge approximately 90 mA h g−1 at 5 A g−1 after 1000 cycles). The good electrochemical performances of the C-doped K4Nb6O17 nanosheets can be attributed to the outstanding 2D structure and large specific surface, which afforded the short transport route for ion and electron. These noteworthy results demonstrated that the new 2D nanomaterials might be potential candidates for the high-performance, environmentally friendly, and low-cost electrochemical energy storage equipment.
