Nano‐Metal‐Organic Frameworks and Nano‐Covalent‐Organic Frameworks: Controllable Synthesis and Applications

Abstract Nanoscale framework materials have attracted extensive attention due to their diverse morphology and good properties, and synthesis methods of different size structures have been reported. Therefore, the relationship between different sizes and performance has become a research hotspot. This paper reviews the controllable synthesis strategies of nano‐metal‐organic frameworks (nano‐MOFs) and nano‐covalent‐organic frameworks (nano‐COFs). Firstly, the synthetic evolution of nano‐frame materials is summarized. Due to their special surface area, regular pores and adjustable structural functions, nano‐frame materials have attracted much attention. Then the preparation methods of nanostructures with different dimensions are introduced. These synthetic strategies provide the basis for the design of novel energy storage and catalytic materials. In addition, the latest advances in the field of energy storage and catalysis are reviewed, with emphasis on the application of nano‐MOFs/COFs in zinc‐, lithium‐, and sodium‐based batteries, as well as supercapacitors.
