| Abstract Scope |
MXenes are a recently discovered family of two-dimensional (2D) early transition metal carbides and carbon-nitrides that have shown many attractive properties and hold great promise for energy storage and other applications. Although many MXenes have been synthesized, most studies have focused on Ti3C2Tx or other single-transition metal MXenes. In addition, studies on the electrochemical properties of solid-solution MXenes are scarce. Here, new vanadium-titanium double transition metal MAX phase and the corresponding MXenes were successfully synthesized. By combining X-ray diffraction, X-ray photoelectron spectroscopy, energy dispersive X-ray spectroscopy. transmission electron microscopy and scanning transmission electron microscopy, we determined the structure and phase purity of vanadium-titanium double transition metal MXene. In addition, this MXene exhibits excellent gravimetric capacitance and long-lasting stability when applied as an electrode for the supercapacitor. This work not only expands the MXenes family, but also provides a strategy for the preparation of solid-solution MXenes. |
