摘要
二维(2D)层状双金属氢氧化物(LDH)具有独特的结构特性,如高纵横比、高比表面积、单向量子限制、层状结构、可调节的插层阴离子/层间距/金属阳离子组成等,进而在不同的应用领域吸引了人们的广泛关注。首先详细讨论了2D LDH的各种制备方法,包括自下而上方法、自上而下方法和溶解-再生长策略。随后,总结了2D LDH在各个领域的应用前景,并选取了部分实际的应用范例进行了重点介绍。最后,介绍了2D LDH的合成和应用中所存在的挑战和将来的发展方向。
Two-dimensional(2D)layered double hydroxides(LDHs)have unique structural features,such as high aspect ratio,high specific surface area,quantum confinement in one direction,layered structure,tunable intercalated anions/interlayer spacing/metal-cation compositions,and so on,have attracted wide attention of researchers.In this paper,various preparation methods of 2D LDHs were discussed in detail,including top-down approach,bottom-up approach,and dissolution-regrowth strategy.Besides,the promising applications of 2D LDHs in various fields were summarized.Furthermore,current challenges and further tasks regarding the synthesis and application of LDHs were also presented.
