“…The HRTEM images reveal the lattice fringe of the nanosheet region and the nanoparticle region (Figure 2e,f, respectively). The lattice fringe in Figure 2e shows crystal plane spacing of about 0.249 nm and 0.237 nm, in accordance with the (020) and (112) planes of Fe2O3 [53]. The lattice fringe in Figure 2f presents interplanar spacing of 0.314 nm, 0.192 nm, and 0.163 nm, relating to the (111), (220), and (311) planes of Si [54].…”

By virtue of the high theoretical capacity of Si, Si-related materials have been developed as promising anode candidates for high-energy-density batteries. During repeated charge/discharge cycling, however, severe volumetric variation induces the pulverization and peeling of active components, causing rapid capacity decay and even development stagnation in high-capacity batteries. In this study, the Si/Fe2O3-anchored rGO framework was prepared by introducing ball milling into a melt spinning and dealloying process. As the Li-ion battery (LIB) anode, it presents a high reversible capacity of 1744.5 mAh g−1 at 200 mA g−1 after 200 cycles and 889.4 mAh g−1 at 5 A g−1 after 500 cycles. The outstanding electrochemical performance is due to the three-dimensional cross-linked porous framework with a high specific surface area, which is helpful to the transmission of ions and electrons. Moreover, with the cooperation of rGO, the volume expansion of Si is effectively alleviated, thus improving cycling stability. The work provides insights for the design and preparation of Si-based materials for high-performance LIB applications.

“…Therefore, CNTs are often used as reinforcement fillers to prepare nanofibers after compounding with other polymers, which can effectively improve the properties of nanofibers. Fe 2 O 3 /C/CNT composites [ 21 ] sprayed by ultrasonic can be used as an anode for lithium-ion batteries. In these composites, the high conductivity of CNTs makes charge transfer faster, which improves the performance of lithium-ion batteries.…”

In response to the exhaustion of traditional energy, green and efficient energy conversion has attracted growing attention. The IVA group elements, especially carbon, are widely distributed and stable in the earth’s crust, and have received a lot of attention from scientists. The low-dimensional structures composed of IVA group elements have special energy band structure and electrical properties, which allow them to show more excellent performance in the fields of energy conversion. In recent years, the diversification of synthesis and optimization of properties of IVA group elements low-dimensional nanomaterials (IVA-LD) contributed to the flourishing development of related fields. This paper reviews the properties and synthesis methods of IVA-LD for energy conversion devices, as well as their current applications in major fields such as ion battery, moisture electricity generation, and solar-driven evaporation. Finally, the prospects and challenges faced by the IVA-LD in the field of energy conversion are discussed.

“…18 Metal chalcogenide (MCs), belonging to conversion anodes, has the adequate properties to be extensively studied. Compared to the corresponding metal oxides, 19–22 MCs demonstrate high capacity while having higher electronic conductivity and more convenient ions transport channels due to the weaker M–C (C denotes S, Se, and Te) bonds in comparison to M–O bonds. 23,24 Moreover, many MCs with two-dimensional (2D) layered structures (MoS 2 , WS 2 , WSe 2 , VS 2 etc. )…”
