Advanced electromagnetic (EM) wave absorbing materials with strong absorption and broad bandwidth are important for military stealth and elimination of microwave pollution in consumers’ electronics. Metal organic framework (MOF)-derived metal/carbon hybrids with ordered structure are significantly urgent in this field. In this contribution, we presented a design strategy of hollow cage-like or solid box-like magnetic/dielectric Fe/Co/C and dielectric Fe/Mn/C EM wave absorbing nanomaterials via pyrolyzing Prussian blue’s analogs with controllable topology and phase composition. The solid box-like Fe/Co/C and hollow cage-like Fe/Mn/C showed favorable absorption property with a broad effective absorption bandwidth (EAB) and a low reflection loss (RL). Especially, the EAB of 8.8 GHz at a thickness of 2.5 mm for solid box-like Fe/Co/C nanocomplex prepared at 900°C is a new record for this type of materials. The design and tuning strategy for EM wave absorbers derived from topology-controllable MOF is important for EM functional materials possessing great potential in military stealth and consumers’ electronics.

具有强大吸收能力和宽带宽的先进电磁（EM）吸波材料对于军事隐形和消除消费者电子设备中的微波污染至关重要。具有有序结构的金属有机骨架（MOF）衍生的金属/碳杂化物在该领域非常迫切。在此贡献中，我们提出中空的设计策略笼状或盒状的磁性/电介质的Fe / CO / C和电介质铁/锰/ C EM固体波吸收纳米材料经由具有可控制的拓扑结构和相组成的普鲁士蓝类似物热解。固态盒状Fe / Co / C和空心笼状Fe / Mn / C表现出良好的吸收性能，具有宽的有效吸收带宽（EAB）和低反射损耗（RL）。尤其是，对于在900°C下制备的固态盒状Fe / Co / C纳米复合材料，厚度为2.5 mm的8.8 GHz EAB是此类材料的新记录。拓扑可控MOF衍生的EM波吸收器的设计和调谐策略对于在军事隐身和消费者电子产品中具有巨大潜力的EM功能材料非常重要。
