摘　　要：近年来发展的太阳能海水淡化技术可有效利用太阳能在界面处进行海水蒸发,有望缓解淡水危机。MXene是一种新兴的二维(2D)纳米材料,具有成分可调、结构可控的特点,能够高效吸收太阳光并将其转化为热能,为太阳能的高效利用提供了新途径。通过将2D MXene纳米片与具有多孔结构(如高分子泡沫、纤维素、水凝胶、碳基材料和生物质基底等)的3D基底相结合,利用孔道结构中大的比表面积向界面输送水份,能够在保留MXene纳米片优良特性的同时实现高效海水淡化。综述了基于MXene光热材料多种综合性能优异的3D太阳能蒸发器及纯MXene水凝胶,为缓解日益严峻的水资源危机提供有意义的参考价值。The solar desalination technology developed in recent years can effectively use solar energy to evaporate seawater at the interface,which is expected to alleviate the fresh water crisis.MXene is an emerging two-dimensional(2D)nanoma⁃terial with adjustable composition and controllable structure,which can absorb sunlight and efficiently convert it into heat energy,providing a new way for efficient utilization of solar energy.By combining 2D MXene nanosheets with 3D substrates with porous structures such as polymer foams,cellulose,hydrogels,carbon-based materials and biomass substrates,the large specific surface area of the pore structure can be used to transport water to the interface,which can achieve efficient desalination while retaining the excellent characteristics of MXene nanosheets.A variety of 3D solar evaporators with excel⁃lent comprehensive properties and pure MXene hydrogels based on MXene photothermal materials are reviewed in this pa⁃per,which provides meaningful reference value for alleviating the increasingly severe water resources crisis.
