Abstract
LDHs have unique laminar structures, large interlaminar spacing ions, and highly adjustable components, which have been widely used in the field of electrochemistry. However, it is still a considerable challenge to regulate the microstructure and electronic structure of LDHs through reasonable design to obtain electrode materials with high activity. In this paper, three novel ternary-layered dihydroxide nano-compounds have been synthesized. Firstly, three LDHs materials (named as FeCoNi-LDHs, FeCoCu-LDHs, and FeCoZn-LDHs, respectively) were prepared by using the ZIF-67 framework material as a precursor by cation exchange strategy. Finally, the applications of these materials as electrode materials in oxygen evolution reactions (OER) and supercapacitors are explored based on current energy problems.
