“…The precursors; polytetrafluoroethylene (PTFE), transition metal oxides (Nb 2 O 5 , V 2 O 5 , TiO 2 , and MoO 3 ), and sodium metal were kept in a stainless-steel autoclave at 600 °C in an electronic furnace for 12 h. After cooling the autoclave, the collected sample was washed with dilute HCl, water, and alcohol and was then dried in an oven at 60 °C for 5 h. Crystal structure and phase purity were verified by XRD results and FESEM, SAED, TEM, and HRTEM were used to study morphologies and microstructures. NbC showed a good crystalline form while the other three carbides showed different dimensions [ 66 ].…”

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 resource utilization of waste plastic can not only control environmental pollution but can also ease up the problems of lack of energy resources. In this study, molybdenum carbide (Mo 2 C) nanoparticles have been synthesized by utilizing waste polyvinyl chloride as a carbon source in a stainless-steel autoclave at 600 °C. X-ray diffraction pattern indicates that the product is orthorhombic phase Mo 2 C. Electron microscopy photographs show that the obtained Mo 2 C product consisted of crystalline nanoparticles with an average size of 50 nm. The possible formation mechanisms of Mo 2 C have been also briefly discussed on the basis of the structures of the products synthesized with different reaction times. The effects of reaction temperature on the crystallinity and microstructure of the obtained products have been investigated. The results show that higher reaction temperature promotes the formation of Mo 2 C with high crystallinity.
