“…Among the transition metal oxides (Co 3 O 4 [30], V 2 O 5 [31], NiO [32,33], SnO 2 [34], MnO 2 [35,36], TiO 2 [37,38], MoO 2 [39]), MnO 2 has become the most promising competitor due to its ultrahigh theoretical specific capacitance, excellent cycle stability, and ideal charge storage characteristics [40,41]. In addition, MXene with good electrical conductivity and mechanical properties can greatly utilize the high theoretical pseudocapacitance of transition metal oxides.…”

The ternary MXene/MnO 2 /polyaniline (PANI) nanostructure was successfully prepared through a simple, scalable, and reproducible two-step method. First, the interlaced layered MnO 2 is grown on the interlayer and surface of MXene through the hydrothermal reaction. And then the composite was covered with conducting polymer PANI through the redox reaction in the ice bath to obtain the ternary MXene/MnO 2 /PANI nanostructure. The accordion-like MXene substrate has good conductivity and provides electron conduction channels. MnO 2 nanosheets not only inhibit the re-stacking of the MXene layer but also form an effective pore space, which is conducive to ion diffusion and transfer. The outer PANI can further improve the electrochemical performance of the composite. The morphology, chemical structure, and crystal phase of the prepared nanostructure were measured in detail by SEM, FTIR, and XRD. In addition, the behavior of the supercapacitor was analyzed through cyclic voltammetry (CV) and galvanostatic charge and discharge (GCD) tests. Test analyses show that the specific capacitance of the MXene/MnO 2 /PANI nanostructure is about 216 F g −1 at a current density of 1 A g −1 . And the capacitance retention rate after 5000 cycles under the two-electrode test system is about 74%.

Magnetic Fe3O4/MnO2/TiO2/polypyrrole (PPy) heterostructure as adsorbent for adsorbing Mn7+ was synthesized by combining hydrothermal method and chemical oxidation method. The heterostructure was characterized by field‐emission scanning electron microscope, Fourier transform infrared spectroscopy, X‐ray diffraction, and vibrating sample magnetometer. Its saturation magnetization is 18.88 emu/g, so it is easy to separate it from the solution. The feasibility of Fe3O4/MnO2/TiO2/PPy heterostructure to remove Mn7+ was researched in detail. It is found that the optimal pH is 2. The initial adsorption rate can reach 4.60 mg/g min. At 288.15 K, the maximum equilibrium adsorption capacity is 202.8 mg/g. Adsorption kinetics follows a pseudo second order model, as well as is determined by through membrane diffusion processes. The Langmuir isotherm model is used to describe the adsorption isotherm behavior. Besides, thermodynamic parameters indicate spontaneous adsorption behavior, and entropy of the endothermic reaction increases. Finally, the cycle test results show that the adsorbent has better cycle performance, displaying broad application prospects.

Flower-like MoS 2 -coated magnetic Fe 3 O 4 /graphite nanosheet (GNs) spheres are used to prepare Fe 3 O 4 /GNs-MoS 2 composites with controllable electromagnetic (EM) wave-absorbing properties. The different particle size of Fe 3 O 4 plays an important role in the formation of Fe 3 O 4 / GNs-MoS 2 . Fe 3 O 4 /GNs-1-MoS 2 exhibits EM wave absorption properties with a minimum reflection loss (RL min ) value of −46.67 dB at 3.3 mm matching thickness; an effective absorption bandwidth (EAB) of 4.56 GHz can be achieved with 2.1 mm matching thickness. Meanwhile, Fe 3 O 4 /GNs-2-MoS 2 exhibits excellent EM wave absorption properties with an RL min of −55.96 dB at 2.1 mm; the EAB is 4.00 GHz at 1.5 mm with ultra-thin thickness. The superior EM wave absorption ability is related to the different morphology of Fe 3 O 4 /GNs-MoS 2 and the synergistic contribution between the various loss mechanisms and good impedance matching. This work explains and proves the prospect that the enhancement of EM wave absorption performance by different microstructures can be adjusted and controlled to enhance the absorption intensity of the composites and to expand their EAB. This is a promising method for manufacturing EM wave-absorbing materials with controllability.
