Two‐Dimensional Metal–Organic Frameworks‐Based Electrocatalysts for Oxygen Evolution and Oxygen Reduction Reactions

Abstract

Due to unique intrinsic properties and flexible structure modulations, 2D metal–organic frameworks (MOFs)‐based materials have become the most promising candidates in the electrocatalysts of energy‐conversion systems such as oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). Herein, the background of fundamental 2D MOFs is first introduced and 2D MOF‐based electrocatalysts are classified based on OER and ORR. Meanwhile, the recent advances in the 2D MOF‐based OER and ORR electrocatalysts are emphasized and discussed including the subtle synthesis strategy, novel structures, unique morphologies, superior electrocatalytic performances, and the underlying reaction mechanism. Finally, the challenges and future perspectives for the developments and research of 2D MOFs‐based OER and ORR electrocatalysts are proposed.
