Metal–organic framework (MOF) derivatives have been widely concerned with its diverse advantages. To break the mindset of magnetic-derivative design, and make up the shortage of monometallic non-magnetic derivatives, we first try non-magnetic bimetallic MOFs derivatives to achieve efficient EMW absorption. The porous carbon-wrapped TiO<sub>2</sub>/ZrTiO<sub>4</sub> composites derived from PCN-415 (TiZr-MOFs) are qualified with a minimum reflection loss of − 67.8&nbsp;dB (2.16&nbsp;mm, 13.0&nbsp;GHz), and a maximum effective absorption bandwidth of 5.9&nbsp;GHz (2.70&nbsp;mm). Through in-depth discussions, the synergy of enhanced interfacial polarization and other attenuation mechanisms in the composites is revealed. Therefore, this work confirms the huge potentials of non-magnetic bimetallic MOFs derivatives in EMW absorption applications.</p><p>Highlights:</p><p>1 Non-magnetic bimetallic MOF-derived porous carbon-wrapped TiO<sub>2</sub>/ZrTiO<sub>4</sub> composites are firstly used for efficient electromagnetic wave absorption.<br>2 The electromagnetic wave absorption mechanisms including enhanced interfacial polarization and essential conductivity are intensively discussed.</p> ER -
