“…Therefore, some groups attempted to fabricate MOFs-based composites by introducing some additional EM components and then converted these composites into magnetic carbon-based microwave absorbers with desirable chemical composition [ 69 , 70 ]. By considering that magnetic loss capability in some MOFs-derived carbon-based composites is usually insufficient, the involvement of additional magnetic components becomes one effective pathway to further reinforce the overall EM properties of these composites [ 71 ]. Wang et al introduced Co nanoparticles during the growth of ZIF-67 crystals, and they did raise the saturation magnetization and magnetic loss capability as compared with Co/C composite from pristine ZIF-67 [ 29 , 72 ].…”

“…Metal-organic frameworks have made significant advancement over the past years by continual modification and shaping to meet the industrial applications. 104 Meanwhile, the essential requirements of MOFs for industrial manufacturing and processing remain unchanged because of the mechanical stress. 72,105 However, MOFs with high porosity usually exhibit weak mechanical stabilities.…”

“…A porous structure with large surface areas and sufficient porosity leads to the lowering of the permittivity [ 123 , 148 ]. On the one hand, the massive continuous hollows serve as polarization centers, further enhancing the dielectric loss ability [ 149 , 150 ]. On the other hand, graphite-like crystal can be prepared with metal catalysis during the pyrolysis, thereby enhancing the dielectric loss ability of the material.…”
