Solvothermally Synthesized Co(CoO)/Ti3C2Tx/TiO2 Nanocomposites for Enhanced Microwave Absorption
Source abstract
Abstract
Ti 3 C 2 T x MXene has already been studied as an appealing microwave absorption material, benefiting from its fascinating laminated structure. Nevertheless, the single absorption mechanism of pure Ti 3 C 2 T x MXene results in poor impedance matching. In this paper, magnetic Co nanoparticles were introduced on Ti 3 C 2 T x MXene by using a simple solvothermal method. By introducing different contents of Co nanoparticles, the impedance matching and magnetic properties of the Co(CoO)/Ti 3 C 2 T x /TiO 2 nanocomposites could be optimized. It is demonstrated that the effective absorption bandwidth of Co(CoO)/Ti 3 C 2 T x /TiO 2 nanocomposites is 5.84 GHz (6.88–12.72 GHz), while the minimum reflection loss is −61.02 dB. Comparatively, our Co(CoO)/Ti 3 C 2 T x /TiO 2 nanocomposites exhibited better satisfied microwave absorption performance. The potential mechanism of microwave absorption was fully explored. Our report provides a simple and safe method to design high-efficiency absorbers which rely on Ti 3 C 2 T x .
