Atmospheric ozone has long been a threat to human health, however, rational design of high-performance O₃-decomposition catalysts remains challenging. Herein, we demonstrate the great potential of a series of isomorphous bimetallic MOFs denoted as PCN-250(Fe₂M) (M = Co²⁺, Ni²⁺, Mn²⁺) in catalytic O₃ decomposition. Particularly, PCN-250(Fe₂Co) showed 100% O₃ removal efficiency for a continuous air flow containing 1 ppm O₃ over a wide humidity range (0 ‒ 80% RH) at room temperature. Mechanism studies suggested that the high catalytic performance originated from the introduction of open Co(II) sites as well as its porous structure. Additionally, at low pressures around 10 Pa, PCN-250(Fe₂Co) exhibited high adsorption capacities (89 ‒ 241 mg g⁻¹) for most VOCs, which are not only a class of hazardous air pollutants but also the precursor of O₃. This work opens up a new avenue to develop advanced air purification materials for O₃ and VOCs removal in one.

大气臭氧长期以来一直威胁着人类健康，然而，合理设计高性能O ₃ -分解催化剂仍然具有挑战性。在此，我们展示了一系列同晶双金属 MOF 的巨大潜力，表示为 PCN-250(Fe ₂ M) (M = Co ²⁺ , Ni ²⁺ , Mn ²⁺ ) 在催化 O ₃分解中的巨大潜力。特别是，PCN-250(Fe ₂ Co)对于含有 1 ppm O ₃的连续气流显示出 100% O _{3去除效率}在室温下的宽湿度范围 (0 ‒ 80% RH) 内。机理研究表明，高催化性能源于开放的 Co(II) 位点及其多孔结构的引入。此外，在 10 Pa 左右的低压下，PCN-250(Fe ₂ Co) 对大多数 VOC 表现出高吸附能力 (89 ‒ 241 mg g ⁻¹ )，VOC 不仅是一类有害空气污染物，也是 O2 的前体₃ . _{这项工作为开发用于 O 3}和 VOCs 去除的先进空气净化材料开辟了一条新途径。
