Abstract:

The accelerating pace of technological advancement and industrialization has propelled electromagnetic radiation protection and heavy metal treatment to the forefront of current research. In this work, we adopted an original one pot green synthesis method, fabricated a set of novel manganese dioxide@nitrogen-doped carbon@NiFe2O4 hybrids. The microstructures and morphologies, crystal forms, chemical compositions, electromagnetic parameters and electromagnetic wave absorption performances of as-synthesized hybrids were investigated in detail. Result of reflection loss curves indicated that the optimized sample obtained by adjusting the dosage of pyrrole monomer exhibited ideal electromagnetic wave absorption efficiency, with a minimum reflection loss value of −48 dB at the sample thickness of 3.2 mm, which can mainly be attributed to the resonance effect caused by interface polarization, reasonable impedance matching and some other factors. The synthesis concept involved in this one pot method is also beneficial for promoting the development of green synthesis.
