Abstract

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.

封面专题：作为可充电锌-空气电池双功能电催化剂的金属有机框架材料（电池与超级电容器 11/2024）

封面特写展示了在液态锌-空气电池系统中发生的催化氧还原（ORR）和氧进化（OER），以及电子的转移和 O2 与 OH- 之间的转换。图中展示了用于可充电锌-空气电池的 MOF 催化剂基本类型的形态。多孔结构和可调化学成分似乎是它们用作电催化剂的主要优势。由 MOF 衍生的碳基材料可作为牺牲模板，具有高活性、导电性和稳定性。在他们的综述（DOI: 10.1002/batt.202400402）中，Z. Sun 及其合作者介绍了三种金属有机骨架双功能催化剂（原始 MOF、MOF 衍生物和复合衍生物），并展示了它们如何为替代贵金属催化剂提供新的可能性。
