摘要
MXenes是一种二维过渡金属碳化物或碳氮化物,其具有类石墨烯结构。通过氢氟酸或者氟盐和盐酸的混合溶液化学刻蚀三元金属碳化物(MAX相)中的过渡金属元素得到新型的MXenes二维材料,其化学通式是M_(n+1)X_nT_X(n=1,2,3……),其中M代表过渡金属元素,X代表碳或碳和氮,T_X代表MXenes片层表面的终止基团,包括-H、-F、-OH。通过对MXenes表面的改性,对层间距的处理,提高质子传输效率,有利于MXenes在电化学方面的应用。该文综述了MXenes的制备及在电化学传感、电池、超级电容器等领域的应用研究进展,并展望了MXenes在电化学领域应用的前景。
MXenes is a two-dimensional transition metal carbide or carbonitride having a graphene-like structure.A new MXenes 2 D material was obtained by chemical etching of transition metal elements in hydrofluoric acid or mixed solution of fluoride salt and hydrochloric acid. The chemical formula is Mn＋1XnTX（n = 1, 2, 3...）, where M represents a transition metal element, X represents carbon or carbon and nitrogen, and TX represents a terminating group on the surface of the MXenes sheet, including-H,-F,-OH. Through the modification of the surface of MXenes, the treatment of interlayer distance and the improvement of proton transfer efficiency, it is in favor of the electrochemical application of MXenes. This review summarizes the progress in the application of MXenes in the fields of electrochemical sensing, batteries, supercapacitors and so on. The prospects for the application of MXenes in the electrochemical field are also reviewed.
