“…The chemical environments of each constituent element are further investigated by deconvoluting their respective spectra. Figure 5a shows C 1s of the Pd/Ni/MOFDC deconvoluted into different spectra at binding energies of 287 (O=C−N), 285 (C−O), 284.6 (C sp 2 / sp 3 ) [32] and 282.2 eV for metallic carbide (M−C) [33, 34]. Similar spectra fitting was obtained for C 1s deconvolution of the Pd/AT‐Ni/MOFDC (Figure 5b), except the metallic carbide peak at 282.2 eV which became flat.…”

Metal-organic framework derived carbon (MOFDC) serves as supporting platforms for PdNi catalyst (Pd/Ni/MOFDC) and acid-treated nickel counterpart (Pd/AT-Ni/MOFDC). The two Pd-based electrocatalysts are tested for alkaline water-splitting (i. e., hydrogen evolution (HER) and oxygen evolution reactions (OER)). The results reveal better HER and OER kinetics for Pd/Ni/MOFDC than Pd/AT-Ni/MOFDC. DFT calculations show that the high performance of the Pd/Ni/MOFDC can be associated with its high conductivity toward adsorbed OH compared to the Pd/AT-Ni/ MOFDC counterpart. The superior overall water-splitting of Pd/Ni/MOFDC describes the synergy between Ni/Ni (OH) 2 interface and nanostructured Pd for possible future application in an electrolyzer.

A Ni-based metal–organic framework (Ni-MOF) has been synthesized using a microwave-assisted strategy and converted to nanostructured Ni/MOF-derived mesoporous carbon (Ni/MOFDC) by carbonization and acid treatment (AT-Ni/MOFDC). The materials are well characterized with Raman, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and Brunauer–Emmett–Teller (BET), revealing that chemical etching confers on the AT-Ni/MOFDC-reduced average nanoparticle size (high surface area) and structural defects including oxygen vacancies. AT-Ni/MOFDC displays low series resistances and a higher specific capacity ( C s ) of 199 mAh g –1 compared to Ni/MOFDC (92 mAh g –1 ). This study shows that the storage mechanism of the Ni-based electrode as a battery-type energy storage (BTES) system can be controlled by both non-faradic and faradic processes and dependent on the sweep rate or current density. AT-Ni/MOFDC reveals mixed contributions at different rates: 75.2% faradic and 24.8% non-faradic contributions at 5 mV s –1 , and 34.1% faradic and 65.9% non-faradic at 50 mV s –1 . The full BTES device was assembled with AT-Ni/MOFDC as the cathode and acetylene black (AB) as the anode. Compared to recent literature, the AT-Ni/MOFDC//AB BTES device exhibits high energy (33 Wh kg –1 ) and high power (983 W kg –1 ) with excellent cycling performance (about 88% capacity retention over 2000 cycles). This new finding opens a window of opportunity for the rational designing of next-generation energy storage devices, supercapatteries, that combine the characteristics of batteries (high energy) and supercapacitors (high power).

“…Nickel oleate was formed from Ni precursor which was then further reacted with the carbon of oleylamine and oleic acid. In this method, oleic acid not only acted as a source of carbon but also as a surfactant for the controlled synthesis of Ni 3 C [ 59 , 60 ]. Liquid phase synthesis of NiC was done in three-neck round bottom flask using Ni-acetylacetonate hydrate and oleylamine as a precursor.…”

Good stability and reproducibility are important factors in determining the place of any material in their respective field and these two factors also enable them to use in various applications. At present, transition metal carbides (TMCs) have high demand either in the two-dimensional (2D) form (MXene) or as nanocomposites, nanoparticles, carbide films, carbide nano-powder, and carbide nanofibers. They have shown good stability at high temperatures in different environments and also have the ability to show adequate reproducibility. Metal carbides have shown a broad spectrum of properties enabling them to engage the modern approach of multifacet material. Several ways have been routed to synthesize metal carbides in their various forms but few of those gain more attention due to their easy approach and better properties. TMCs find applications in various fields, such as catalysts, absorbents, bio-sensors, pesticides, electrogenerated chemiluminescence (ECL), anti-pollution and anti-bacterial agents, and in tumor detection. This article highlights some recent developments in the synthesis methods and applications of TMCs in various fields.
