摘要
MXenes因其独特的表面化学性质、可调的金属组份、良好的亲水性和较高的载流子浓度,近年来被广泛应用于诸多研究领域.与其他二维材料类似,MXenes可与其他材料进行复合构建异质结,形成MXenes基三维多孔材料,从而显著增强其反应活性,提升其相关性能.尤其是这些三维多孔MXenes材料所具有的三维结构和明确的孔径,可显著提高电化学过程中各种离子和电子的传输速率,因此在电化学能量存储、传感、催化和环境领域应用前景广阔.在这篇综述中,作者以MXenes/碳、MXenes/无机物和MXenes/聚合物这三种主要的MXenes基异质结为研究对象,系统地总结了近年来三维多孔MXenes基异质结的构建方法的研究进展.同时,深入探讨了三维多孔MXenes基异质结在光催化、环境监测和电化学储能中的应用进展.最后,详细归纳了三维多孔MXenes基异质结的孔隙形成机制、性质和应用之间的关系,并提出了作者独到的见解.本综述可为三维多孔MXenes基异质结在高性能材料和器件中的设计、制造和应用等方面提供指导.
Due to their unique surface chemistry,highly adjustable metal components,hydrophilicity,and high carrier concentrations,MXenes are applied in a variety of scenarios.Similar to other two-dimensional(2D)materials,building heterostructures with additional materials to form a 3D porous architecture for MXenes can significantly enhance their functionality and reactivity.Notably,the open structures and well-defined pathways of these 3D structured MXenes can improve ionic and electronic transport,thereby promoting their applications in electrochemical energy storage,sensing,catalysis,and environment.In this review,the recent efforts made on preparing 3D porous MXenes with heterostructures,focusing on MXenes/C,MXenes/inorganics,and MXenes/polymers were summarized.The discussion covers aspects ranging from the design to synthesis of 3D porous MXenes,and their applications in photocatalysis,environmental monitoring and electrochemical energy storage.This review is concluded by presenting the prospects and insights on exploring the relationships between the porosity formation mechanisms,properties and applications of the 3D porous MXenes heterostructures.This review can provide meaningful guidance for the design,fabrication and application of 3D porous MXenes in high-performance materials and devices.
