Electromagnetic wave absorbing performances with Fe2O3 nanotubes/reduced graphene oxide composite sponge

Flower-like 1T/2H-MoS2@α-Fe2O3 with enhanced electromagnetic wave absorption capabilities in the low frequency range

“…Notably, the two typical satellite peaks at 730.1 eV and 714.2 eV were assigned to the spin-orbit splitting of Fe 2p 1/2 and Fe 2p 3/2 bands, respectively. 30,31 For the XPS spectrum of O1 s in Fig. 3d, the prominent spectra at 530.4 and 529.3 eV can be thought of the oxygen vacancies and the oxygen of the Fe-O bond, respectively.…”

Optimized electromagnetic wave absorption of α-Fe2O3@MoS2 nanocomposites with core–shell structure

“…Zhang et al reported the preparation of Fe 2 O 3 -MW-4h nanoparticles with multi-cavity structure by a microwave-assisted template process, which can be used as anode materials for lithium ion batteries with promising applications [16]. Moreover, Fe 2 O 3 with various nanostructures such as nanocubes [7], nanorings [17], nanorods [9], nanotubes [18], and so on has also enhanced microwave absorption performance. Therefore, it can be seen that Fe 2 O 3 is considered as an absorber to achieve an outstanding electromagnetic wave absorbing effect due to the rich interfacial structure that can improve impedance matching.…”

“…In order to provide as many electromagnetic waves as possible to the absorber, the electromagnetic waves are completely attenuated to achieve remarkable electromagnetic wave absorption capabilities. Thus, more free space is needed so that the electromagnetic waves can be reflected multiple times and thus achieve more attenuation [18]. It is therefore of supreme importance to obtaining excellent electromagnetic wave absorption capabilities that the nanocomposites and rich structures of absorbing materials should be considered.…”
