摘要
Manganese-based heterostructured nanocomposites have attracted extensive attention due to their abundant interfaces and controllable multi-component synergistic absorption mechanisms resulting in excellent microwave absorption properties. However, the development of the dual manganese containing magnetic/dielectric heterojunctions and the controllable construction of their heterointerfaces and defects still faces great challenges and remains unrealized. Herein, we successfully synthesized carbon-coated MnFe2O4/MnO heterojunction nanocomposites with foam-like macroporous structures for high-performance microwave absorption. The optimized absorber with controlling the MnFe2O4/MnO heterojunction to reach the maximum amount exhibits the excellent absorption performance: the strongest reflection loss (RL) value can reach -72.1 dB at 10.45 GHz; the widest effective absorption (RL <-10 dB) bandwidth (EAB) is 5.01 GHz (8.39-13.4 GHz) at 2.83 mm; the EABs at different thicknesses (2-3.1 mm) are all above 4 GHz. Despite multiple loss mechanisms, this brilliant performance is determined and dominated by the modulation of heterointerfaces and defect sites. Inspiringly, our inventive in-situ construction of heterointerfaces and defects provides a new perspective for heterojunction engineering to achieve remarkable microwave absorption properties.
