Hierarchical 0D/2D NiFe2O4/Ti3C2Tx MXene composites for boosting microwave absorption

MXene-based microwave absorption materials (MAMs) are considered an effective strategy to eliminate or decrease electromagnetic pollution. Herein, an attempt was made to construct 0D/2D NiFe2O4/Ti3C2Tx composites by one-step solvothermal method using ethylene glycol as solvent, which effectively inhibited the oxidation of Ti3C2Tx. The results showed that the NiFe2O4/Ti3C2Tx composites coupling magnetic NiFe2O4 with dielectric Ti3C2Tx exhibited excellent microwave absorption performance. The minimum reflection loss (RLmin) of −54.75 dB and effective absorption bandwidth (EAB) of 2.08 GHz were obtained at a thickness of 2.5 mm for 20 %NiFe2O4/Ti3C2Tx composite. The possible mechanisms are discussed in detail.
