摘要

Two-dimensional nanomaterial MXene Ti3C2Tx with excellent electrical conductivity has received extensive attention in the electromagnetic wave (EMW) absorption field. However, the excessively high permittivity of Ti3C2Tx is not conducive to impedance matching and the absorption of EMW. Considering the low permittivity and mesoporous structure of MOF, in this work, Co/La-MOF were in situ growth on the surfaces of Ti3C2Tx by a facile co-solvothermal method. The obtained Co/La-MOF anchored on Ti3C2Tx (Co/La-MOF/Ti3C2Tx) composite exhibits low density with excellent EMW absorption performance. Co/La-MOF/Ti3C2Tx-2 (Co2+/La3+ mass ratio of 16:3) shows the minimum reflection loss of − 44.15 dB at 4.00 GHz with the effective absorption bandwidth of 3.67 GHz in the frequency range of 14.03–17.70 GHz under 1.3 mm. In addition, the electromagnetic absorption mechanism of Co/La-MOF/Ti3C2Tx was also investigated. It provides an effective strategy for the preparation of a novel absorber with high EMW absorbing performance.
