Synthesis of V2C MXene: Effects of Etchant Concentration on Material Applications
摘要
MXenes, a rapidly growing family of two-dimensional (2D) transition metal carbides and nitrides, have garnered significant attention due to their unique properties and potential applications across various fields. Vanadium-based MXenes (V-MXenes) are particularly noteworthy due to their excellent electrochemical performance. Their special qualities, which include high surface area and capacity to promote quick ion transport, help explain why they work so well in electro-catalysis, supercapacitors, and batteries, among other applications. This study reports the synthesis of V₂C MXene through controlled etching using different HF concentrations. X-ray diffraction (XRD) confirmed the removal of aluminum layers and successful V₂C formation, with characteristic peaks of the (002) plane. UV-visible spectroscopy indicated promising optical properties, suggesting suitability for supercapacitors. These findings contribute to optimizing MXene synthesis methods for applications in catalysis, energy storage, and advanced electronics. Improved synthesis methods reduce the reliance on hazardous hydrofluoric acid (HF) and energy intensive processes in turn making fabrication of MXene more environmental friendly and cost effective.
