Preparation of Fluorine-free MXene Ti₃C₂T _x and Its Electrical Properties

Abstract

The fluorine-free MXene was prepared by Lewis acid salt etching of ternary layered ceramic MAX phase material. The structure of fluorine-free MXene was characterized by scanning electron microscopy (SEM) and X-ray diffractometry (XRD). The study finds that the layer spacing of fluorine-free MXene is approximately twice that of MXene etched by the liquid-phase method, compared to the conventional liquid-phase method. It also has greater capacitive properties. Therefore, the MXene prepared by this method shows a great potential for application in the field of capacitors.
