Two-dimensional metal-organic framework materials for energy conversion and storage

Selecting and assembling metal ions and bridging ligands can fabricate two-dimensional metal-organic framework nanosheets, which can act as prospective materials for efficient energy applications. Thanks to large surface area and more porosity, ultrathin 2D MOFs nanosheets and their derived two-dimensional nanosheet materials exhibit more highly approachable active sites uncovered on the surface, decreased ion diffusion distance and fast electron transfer for energy storage/conversion applications. Herein, this review will summarize the latest developments with discussion of design, fabrication, energy storage as well as conversion performance of 2D MOFs and their-derived two-dimensional materials. Moreover, the development of exfoliated two-dimensional MOFs and their derivatives, as well as the promising trends and prospects in application as excellent-performance electrode materials in batteries, supercapacitors, and electrocatalysis are also present.
