摘要
本文对比了二维过渡金属碳(氮)化合物(MXene)的制备方法(氢氟酸刻蚀法、高温刻蚀法和化学气相沉积法);分析了层间距、表面基团和测试环境对MXene材料电化学储能性能的影响,探讨了其结构与电化学储能性能的关系,揭示了不同基体的物理化学性质、微观结构以及基体组成对MXene基复合材料电化学性能的影响。对MXene目前在储能领域应用上存在的问题及未来的发展方向进行了展望。
Two-dimensional(2D)transition metal carbides(denoted as MXenes)as a new member in the family of 2D materials have received considerable attention due to their fascinating physicochemical properties and special structure.To understand their progress in the field of electrochemical energy storage,exciting reports and data published recently were collected,organized,analyzed and concluded in the review.Firstly,several fabrication methods to prepare the Mxene materials including hydrofluoric acid etching,high temperature etching,and the chemical vapor deposition were presented and compared;Secondly,the factors such as interlayer distance,surface functional group,and testing environment were discussed to see how to influence the properties of electrochemical energy storage.Thirdly,various constitution,structure and properties of surface-modified MXenes and their composites were clarified from a structural design point of view.Finally,based on the characteristics of MXene materials,this critical review will not only list potential problems and the future challenge on energy storage devices but will also provide important guidance for the design of promising electrochemical applications of MXene materials.
