| Abstract Scope |
MXenes promise for a wide variety of applications such as energy generation and storage. Chemical Vapor Deposition (CVD) is a surface deposition technique that can be used to form thin layers of carbides as precursors to MXense without the use of hydrofluoric acid for etch exfoliation. In this research, we demonstrate the CVD approach to develop stable MXene precursors in the form of MxC(x-1) (M= Mo, Nb, and V). A computational and theoretical approach was used to evaluate the possibility of the formation of the materials, then experimental synthesis was performed to evaluate the predictions. The formation and composition of carbides was investigated using XRD, EDS and Raman spectroscopy. The results demonstrate the potential of this technique to design and produce modified MXene for versatile applications, as well as fundamental challenges in understanding the thermodynamics and kinetics of the synthesis process. |
