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.

“…The intensity of the peaks decreased, and the patterns broadened evidently with the decline of temperature, indicating that the size of the MoC 1– x particles decreased according to the Scherrer formula. As far as we know, the decomposition temperature of the Mo-containing precursor used in most previous reports is above 700 °C to obtain crystalline MoC 1– x . , Our precursor, by contrast, can produce well-crystalized MoC 1– x nanoparticles even at 600 °C, a relatively low temperature permitting the formation of the smallest crystalline MoC 1– x nanodots in comparison to those in other studies. As indicated in Figure S4, the decomposed sample failed to crystallize when the temperature was reduced to 500 °C.…”

In this study, in situ synthesis of carbon-coated MoC 1−x nanodots anchored on nitrogen-doped carbon (MoC 1−x @ C) for lithium storage is reported. The obtained MoC 1−x @C hybrids exhibit intriguing structural characteristics including ultrafine particle size (ca. 1.2 nm) of MoC 1−x nanodots, porous structure of nitrogendoped carbon matrix, and good robustness. When evaluated as anodes for lithium-ion batteries, the optimized MoC 1−x @C sample demonstrates a superior specific capacity (1099.2 mA h g −1 at 0.1 A g −1 ) and good rate capability (369.1 mA h g −1 at 5 A g −1 ). The MoC 1−x @C anode also presents remarkable cycling stability with a much higher specific capacity (657.9 mA h g −1 ) than that of commercial bulk MoC (91.4 mA h g −1 ) after 500 cycles at 1 A g −1 . Kinetics analysis of the anodes reveals the charge storage mechanism, which demonstrates the existence of capacitive redox reactions occurring at the shallow surface of the MoC 1−x nanodots and closely relating to the particle size. The outstanding electrochemical performance results from the synergistic effect of the elastic carbonaceous encapsulation to accommodate the huge volume expansion and the ultrafine MoC 1−x nanodots to provide more reactive sites for capacitive lithium storage.
