“…The dielectric loss tangent (tan d dielectric and magnetic losses, generally, a higher value represents more energy loss due to its conversion to thermal energy or other form of energy. 54,55 As displayed in Fig. 9a, for all samples, the values of dielectric loss tangent are higher than those of magnetic loss tangent except for small scale of frequency domain, making clear that dielectric loss makes a major contribution to the attenuation of electromagnetic wave.…”

a Developing electromagnetic wave absorbing materials prepared by a facile and economical way is a great challenge. Herein, we report a feasible route to synthesize a series of two-dimensional FeNi/rGO composites by a hydrothermal method followed by a carbonization process. The characterization confirms that nano-sized FeNi alloy nanoparticles are evenly supported onto graphene sheets without aggregation. The homogeneous dispersion of the nanoparticles may result from the introduction of glucose and the oxygen-containing groups on the surface of the graphene oxide. Measurements show that the microwave attenuation capability of the composites can be improved dramatically by adjusting the proportion of dielectric and magnetic components. Consequently, the two-dimensional magnetic material (FeNi/rGO-100) exhibits an excellent microwave absorption performance. In detail, the minimum reflection loss of À42.6 dB and effective bandwidth of 4.0 GHz can be reached with a thinner thickness of 1.5 mm. This study demonstrates that synergistic effects among the magnetic particles, reduced graphene oxide and amorphous carbon layers give rise to the highlighted microwave attenuation ability. Overall, the FeNi/rGO composite is a promising candidate to be used as a microwave absorber, and the feasible and economical method has shown potential application to construct multitudinous two-dimensional materials.

“…If the CNTs are modified with a positively charged surface the reaction is easier than with uncharged CNTs. [157] Because the catalyst is attached to the surface of the Ti 3 C 2 T x flake, the yielded CNTs bridge the widespread Ti 3 C 2 T x flakes and increasingly generate cross links, which further build the porous network. [153] Ti 2 CT x , which is similar to Ti 3 C 2 T x , can also directly generate Ti 2 CT x /CNT composites with CNTs under ultrasonic stirring.…”

“…[70,75,132,148,151,152] MXene/CNT composites can adsorb other function materials, such as in Ti 3 C 2 T x /CNTs/S composite, where sulfur is a cathode material for lithium-sulfur batteries. [157] Zhu and co-workers also synthesized Ti 3 C 2 T x /CNT composites at high temperature with different properties from those in the study by Li et al [156,157] Figure 4a shows a schematic of the preparation process for Ti 3 C 2 T x /CNT composites. [154] Similar composites can also be prepared by alternating filtration of two precursor solutions and exhibit a distinctly ordered alternating structure.…”

“…[215] The surfaces of the MXene layers have many active sites, [137,219] which can be influenced by some substances, such as some specific molecules, [203] temperature variation, [203] light, [163] and so on. [157] Besides the above applications, MXene-based composites are being applied in the field effect transistors, water purification, or to increase Raman spectral sensitivity (surface-enhanced Raman spectroscopy (SER)), and so on. Therefore, the MXene-based composites apply in the biosensor, [189,221] and optical/electronic devices.…”

The family of 2D transition metal carbides, nitrides, and carbonitrides (collectively called MXenes) is rapidly studied since the initial synthesis of Ti3C2Tx (MXene). The surface of MXenes etched by hydrofluoric acid has hydrophilic groups (F, OH, and O), which leads the surface to be negatively charged. Consequently, the negatively charged surface can facilitate the compounding of MXenes with other positively charged materials and prevent MXenes from aggregating with some negatively charged substances, thus promoting the formation of a stable dispersion. The MXene‐based composites have better electrochemical performance than both precursors due to synergistic effects. This review elaborates and discusses the development of MXene‐based composites. It is aimed to summarize the various methods of fabricating MXene‐based composites. The applications of MXene‐based composites in batteries and supercapacitors are presented along with analysis of their excellent electrochemical performances. Finally, the authors propose the approach for further enhancing the electrochemical performances of MXene‐based composite electrode materials.

Novel nanomaterials and advanced nanotechnology continuously push forwardt he rapid development of sustainable energy conversion and storage equipment. An emerging family of two-dimensional transition-metal carbides, nitrides and carbonitrides, also known as MXenes, have attracted increasing attention and in depth investigation. Benefitting from their unique intrinsic properties, MXenes have attracted significant attention and they have been considered as promising candidate materials for the development of environmentally friendly energy resources. Al arge number of studies show that MXenes have great potential in energy conversiona nd storagef ields. Despite of their exceptional properties, MXenes also have some inher-ent characteristics, such as low capacities and unstabler etention performances, which severely hinder their prospect applicationsi ne nergy conversion and storage fields. In this Minireview,t he latest progress on MXenes and their hybrid composites with small molecules, polymers, carbon or metal ions, and their applicationsinenergy conversionand storage fields is highlighted, including their use in different types of batteries, supercapacitors, hydrogen/oxygene volution reactions, electromagnetic interference absorption/shielding and solar steam generation.
