Highly efficient electrocatalysts play important roles in electrochemical water splitting for hydrogen production, including the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). Metal-organic frameworks (MOFs) are porous crystalline materials, exhibiting strong potential as precursors for obtaining outstanding electrocatalysts. MOF-based electrocatalysts, including MOFs and MOF-derived electrocatalysts, have become an increasingly important part of catalysts in the field of electrochemical water splitting, but their catalytic performance, especially their activity and stability, still have a lot of room for improvement. In this paper, the preparation strategy of MOF-based electrocatalysts and improvement methods of catalytic properties were reviewed, including morphology-controlled methods and composition-controlled methods. We also focused on the structure-property relationships, which determine the electrocatalytic activity for water splitting reactions. Finally, the challenges and development prospects were discussed for the MOF-based electrocatalysts, which might provide some insight for future applications in electrochemical water splitting.
