Cover Feature: Metal‐Organic Framework Materials as Bifunctional Electrocatalyst for Rechargeable Zn‐Air Batteries (Batteries & Supercaps 11/2024)

The Cover Feature shows catalytic oxygen reduction (ORR) and oxygen evolution (OER) taking place in a liquid zinc–air battery system with the transfer of electrons and conversion between O2 and OH−. The morphologies of the basic types of MOF catalysts for rechargeable zinc–air batteries are illustrated. Their porous structure and tunable chemical composition seem to be the main advantages for their use as electrocatalysts. Carbon-based materials derived from the MOF act as sacrificial templates with high activity, electrical conductivity and stability. In their Review (DOI: 10.1002/batt.202400402), Z. Sun and co-workers present three kinds of metal–organic skeleton bifunctional catalysts (pristine MOFs, MOF derivatives and composite derivatives) and show how they offer new possibilities for replacing noble metal catalysts.
