In this work, novel sandwich-like 2D laminated Fe&amp;TiO<sub>2</sub> nanoparticles@C nanocomposites were rationally designed and successfully developed from the MXene–MOFs hybrids. The formation of Fe and rutile-TiO<sub>2</sub> nanoparticles sandwiched by the two-dimensional carbon nanosheets provided strong electromagnetic energy attenuation and good impedance matching for electromagnetic wave (EMW) absorption. As expected, the nanocomposites achieved a broad effective absorption bandwidth of 6.5&nbsp;GHz at a thickness of only 1.6&nbsp;mm and the minimum reflection loss (<em>RL</em>) value of − 51.8&nbsp;dB at 6.6&nbsp;GHz with a thickness of 3&nbsp;mm. This work not only provides a good design and fabricating concept for the laminated metal and functional nanoparticles@C nanocomposites with good EMW absorption, but also offers an important guideline to fabricate various two-dimensional nanocomposites derived from the MXene precursors.</p> <p>Highlights:</p> <p>1 Sandwich-like laminated Fe&amp;TiO<sub>2</sub>@C nanocomposites were successfully prepared from the MXene–MOFs hybrids.<br>2 A broad effective bandwidth of 6.5 GHz at a thickness of only 1.6 mm was achieved.</p>}, journal={Nano-Micro Letters}, author={Deng, Baiwen and Xiang, Zhen and Xiong, Juan and Liu, Zhicheng and Yu, Lunzhou and Lu, Wei}, year={2020}, month={Feb.}, pages={55} }
