Micro/nano metal–organic frameworks meet energy chemistry: A review of materials synthesis and applications

Micro/nano metal–organic frameworks (MOFs) have attracted significant attention in recent years due to their numerous unique properties, with many synthetic methods and strategies being reported for constructing MOFs with specific micro/nano structures. In addition, the design of micro/nano MOFs for energy storage and conversion applications and the study of the structure–activity relationship have also become research hotspots. Herein, a comprehensive overview of the recent progress on micro/nano MOFs is presented. We begin with a brief introduction to the various synthesis methods for controlling the morphology of micro/nano MOFs. Subsequently, the structure-dependent properties of micro/nano MOFs as electrode materials or catalysts in terms of batteries, supercapacitors, and catalysis are discussed. Finally, the remaining challenges and future perspectives in this field are presented. Overall, this review is expected to inspire the design of advanced micro/nano MOFs for efficient energy storage and conversion technologies.
