Harvesting yolk-shell nanocomposites from Fe-MIL-101 self-template in NaCl/KCl molten salt environment for high-performance microwave absorber

Progress of metal organic frameworks-based composites in electromagnetic wave absorption

“…The widespread use of electronic equipment and communication equipment inevitably leads to the deterioration of the electromagnetic environment. The electromagnetic waves can cause serious electromagnetic pollution [1][2][3][4][5]. On the one hand, electromagnetic waves will cause interference to some precision equipment, which gives rise to the failure of the instrument and the interruption of the signal not only interrupting the normal work, but may also causing immeasurable harm [6][7][8][9][10], on the other hand, the leaked electromagnetic waves cause certain harm to human health such as cancer [11][12][13][14].…”

Binary molten salt in situ synthesis of sandwich‐structure hybrids of hollow β‐Mo2C nanotubes and N‐doped carbon nanosheets for hydrogen evolution reaction

“…Among them, the appropriate co‐melting point of the NaCl/KCl system (657°C) is very close to the formation temperature of molybdenum carbide with good crystallinity (>700°C) 28 . Moreover, the reaction environment is highly conducive to the construction of the composite structure, since the phase transition occurs easily when the temperature exceeds the eutectic point 29 …”

“…28 Moreover, the reaction environment is highly conducive to the construction of the composite structure, since the phase transition occurs easily when the temperature exceeds the eutectic point. 29 Herein, we reported a scalable MS synthesis strategy to successfully fabricate unique three-dimensional (3D) sandwich-structure hybrids (denoted MS-Mo 2 C@NCNS) consisting of β-Mo 2 C hollow nanotubes (HNTs) and N-doped carbon nanosheets (NCNSs) as cost-efficiency electrocatalysts toward HER. The MS here not only provided a melting environment and increased the fluidity of elements but also played a role in shaping the template.…”
