N, O‐Doped Walnut‐Like Porous Carbon Composite Microspheres Loaded with Fe/Co Nanoparticles for Adjustable Electromagnetic Wave Absorption

“…[17] Preparation methods for hollow porous carbon microspheres often involve template etching or organic solvents. [18] Liang et al [19] prepared porous Fe 4 N/carbon hollow microspheres using the solvothermal method with isopropyl as solvent and pyrolysis method, reaching an RL min of −42.2 dB with a 1.4 mm thickness and an EAB of 4.5 GHz. Similarly, Xiang et al [20] fabricated porous heterogeneous SiC/SiO 2 microspheres based on the self-assembly technology and carbothermal reduction strategy, achieving an RL min of −54.68 dB and an EAB of 8.49 GHz.…”

Recent progress in TiO2-based microwave absorption materials

“…Thus, microwave absorbers have attracted considerable attention in recent years, which are considered a promising and effective tactics to ameliorate EM wave pollution. [1][2][3][4][5][6][7] Nowadays, the development trend of microwave absorbers is light, wide frequency, strong absorption, and heat resistance. Traditional wave-absorbing materials, such as ferrite, magnetic metals, and carbon, cannot meet the above-men-tioned requirements.…”
