层状双氢氧化物（LDH）是一类具有水镁石状层和插层阴离子的粘土。第一个 (3d) 系列基于过渡金属的 LDH (TM-LDH) 由于其独特的物理化学性质，在能量转换和存储过程领域引起了越来越多的兴趣。在本文中，我们回顾了TM-LDH在水分解、CO2转化、金属-空气电池和超级电容器等领域的合成和应用的最新进展以及这些过程的基本机制。此外，从材料设计和性能的角度讨论了当前的挑战和可能的策略。
Layered double hydroxides (LDHs) are a class of clays with brucite like layers and intercalated anions. The first (3d) series transition metals based LDHs (TM-LDHs) are attracting increasing interest in the field of energy conversion and storage processes due to their unique physicochemical properties. In this article, we review recent developments in the synthesis and applications of TM-LDH in these areas including water splitting, CO2 conversion, metal-air batteries and supercapacitors and the underlying mechanisms of these processes. In addition, current challenges and possible strategies are discussed from the viewpoint of material design and performance.
