Preparation of MXene and its application and research progress in supercapacitors

Abstract

As a new type of two-dimensional nanomaterial, two-dimensional transition metal carbon/nitride (MXene) has attracted much attention because of its high specific surface area, high conductivity and solvability. MXene is often used as a basic material to construct macroscopic composites. In recent years, it has been used to manufacture MXene structural-functional integrated fiber materials and mqd derivatives of MXene, which has a wide application prospect in multifunctional fibers, energy conversion and storage (ECS), sensors, catalysis and lubrication, electromagnetic shielding (EMI), supercapacitors (SCs) and so on. And has achieved some results. In this paper, the international research progress of MXene materials in recent years is reviewed, and its structure, properties and preparation methods are summarized. On this basis, its development in the field of energy storage (such as supercapacitors) is summarized, the shortcomings in this field are pointed out, and the future development trend is prospected.
