Summary: Metal-organic frameworks (MOFs) have shown promising potential as electrode materials for the oxygen evolution reaction (OER). This study revealed that MOFs with tetrahedral Co sites exhibit continuous active sites in the OER, while those with octahedral sites are inert. Co-N coordination is more favorable for electrochemical activation than Co-O coordination, leading to the gradual increase in activity of the MOF in the OER process.

Summary: This study investigates the OER performance of Co-based bimetallic MOFs on carbon cloth, comparing different metal combinations. The results show that CoZn MOFs exhibit the best OER performance, attributed to the higher oxidation state of Co and the choice of second metal. Theoretical calculations suggest that tuning the electronic structure of the metal site can be an effective strategy for enhancing OER activity in MOFs.

Summary: By utilizing the isolating effect of cobalt single atoms on platinum, strong interaction between cobalt single atoms and platinum, and the confinement of the metal organic framework-derived porous carbon matrix, platinum nanoparticles were successfully evenly immobilized on a nitrogen-doped carbon matrix with rich cobalt single atoms as multiple active sites. This not only increased the active centers, but also promoted catalysis kinetics, significantly improving catalytic activity for oxygen reduction and hydrogen evolution reactions.

Summary: In this study, core-shelled hybrids of covalent organic frameworks and metal-organic frameworks are constructed to catalyze the oxygen evolution reaction. The high oxygen evolution reaction activity in the core-shelled Co-COF@MOF catalyst is due to the synergetic roles between the Co and Fe sites, which promote the formation of O* from OH*.

Summary: NF/Co3O4/CoFe2O4 composite electrode was synthesized from a metal-organic framework and showed enhanced electrocatalytic activity for the oxygen evolution reaction in alkaline medium. The presence of Co3+ and Fe3+ in the octahedral sites of Co3O4 and CoFe2O4 was attributed to the enhanced OER activity, leading to stable current density and activity over multiple OER experiments.
