“…The MOFs can not only facilitate the exposure of the Ni–S surface but also modify the local environment of the active Ni–S catalyst. He et al prepared a bifunctional electrocatalyst by coating various Co III and Co II contents onto the surface of MIL-101(Cr) with oxidative or reductive treatment during the impregnation. , The electrocatalytic activities of the Co/MIL-101(Cr) composites are closely dependent on the contents of Co III and Co II on the surface. A higher content of Co III is favorable to adsorb O on the surface of electrocatalyst, thus improving the OER activity.…”

In recent years, metal–organic frameworks (MOFs) have been wildly studied as heterogeneous catalysts due to their diversity of structures and outstanding physical and chemical properties. Meanwhile, MOFs have also been regarded as promising templates for the synthesis of conductive and electrochemically active catalysts. However, in most of the studies, high-temperature annealing is needed to transform nonconductive or low-conductive MOFs to conductive materials for electrocatalyis, during which the unique structures and intrinsic active sites in MOFs can be easily destroyed. Therefore, in recent years, different strategies have been developed for improving the catalytic performances of MOF-based composites for electrochemical reactions with no need of post-treatment. This mini-review highlights the recent advances on MOF-based structures with improved conductivities and electrochemical activities for the application in electrocatalysis. Overall, the advanced MOF-based electrocatalysts include the highly conductive and electrochemically active pristine MOFs, MOFs combined with conductive substrates, and MOFs hybridized with active materials. Finally, we propose the direction for future works on MOF-based electrocatalysts.
