Recent advances in metal-organic frameworks derived electrocatalysts for oxygen reduction reaction

Advanced design strategies for Fe-based metal–organic framework-derived electrocatalysts toward high-performance Zn–air batteries

“…The high crystalline topological structure formed by the combination of organic ligands and central metals results in the presence of large pores inside the MOF. 33,55 The porous MOF structure means that the sample has a large active surface area, which is beneficial to form good contact with electrolytes and oxygen-containing reactants, and for full exposure to active sites. At the same time, the interconnected porous network and the mass transfer path are conducive to the transfer of generated oxygen and ensure the continuity of the mass transfer process.…”

First-principles studies of enhanced oxygen reduction reactions on graphene- and nitrogen-doped graphene-coated platinum surfaces

“…16–18 This might be due to the electronic structure of Pt-based alloys being different from that of pure Pt, resulting in significant changes in how reactants and catalysts bond together and thereby improving ORR activity. Alternatively, materials derived from metal–organic frameworks (MOFs), offering large specific surface areas and different pore sizes, 19–21 as well as single-atom catalysts with tunable electronic structures, 22–28 are promising for further exploration of ORR electrocatalysis.…”

Structural Transition in the Growth of Copper Terephthalate Metal–Organic Frameworks: Understanding the Effect of the Synthetic Protocol and Its Impact on Electrochemical Behavior

“…The sustainability of human society depends on the development of new renewable and clean energy systems [1][2][3]. Against this backdrop, electrochemistry offers green and efficient technological alternatives for energy storage and conversion, fuel production and environmental protection [1,2].…”

“…However, these half-reactions have very slow kinetics, which is why they require large overpotentials and excessive amounts of energy to be carried out, and in some cases obtain cell potentials and powers much lower than the theoretical values [1,4]. To overcome this barrier and improve the efficiency of current energy devices, the search for new electrocatalysts that are more economical, stable, efficient 2 of 19 and capable of significantly promoting these electrochemical reactions is crucial [1,[3][4][5]. A promising alternative are metalloenzymes such as cytochrome c oxidase and multicopper oxidases, which are capable of activating, reducing and transporting oxygen efficiently and selectively using multinuclear iron and/or copper complexes as active sites [6][7][8].…”

“…Considering the structural design of bio-electrocatalysts present in nature, different functional materials based on 3D transition metals have been explored as new electrocatalysts. Among these, metal-organic frameworks (MOFs) have begun to show increasing promise in the field of electrocatalysis [1,[3][4][5].…”
