Iron oxides, such as hematite (α-Fe2O3), maghemite (γ-Fe2O3), and magnetite (Fe3O4), have been considered as alternative anode materials for lithium-ion batteries (LIBs) due to their high theoretical capacity, abundant reserves, low cost, and non-toxicity. However, their practical application has been hampered by the large volume expansion, which leads to rapid capacity fading. Nanostructure engineering has been demonstrated to be an effective avenue in tackling the volume variation issue and boosting the electrochemical performances. Herein, recent advances on nanostructure engineering of iron oxides for lithium storage are summarized. These nanostructures include 0D nanoparticles, 1D nanowires/nanorods/ nanofibers/nanotubes, 2D nanoflakes/nanosheets, as well as 3D porous/hollow/hierarchical architectures. The structureelectrochemical performance correlations are also discussed. It is believed that the performance optimization strategies summarized here might be extended to other high-capacity LIB anode materials.

Journal of Advanced Chemical EngineeringLima et al., J Adv Chem Eng 2017, 7:1 DOI: 10.4172/2090 Volume AbstractCore-shell Fe 3 O 4 @C nanoparticles consist of a magnetic core and carbon coating, and exhibit high adsorptive capacity, easy magnetic separation and reusability. Due to these properties, core-shell Fe 3 O 4 @C nanoparticles have great potential application in adsorption, separation and wastewater treatment. Magnetic separation based on the super paramagnetic Fe 3 O 4 has received considerable attention and is widely used for the removal of dye, oil pharmaceuticals and metals from water due to its high efficiency and economic viability. Therefore, the main characteristics of the core-shell Fe 3 O 4 @C nanoparticles, the different types of synthesis, as well as the main applications for the removal of water pollutants were reviewed. In this brief review, an overview of the basic properties of the Fe 3 O 4 @C core-shell nanoparticles are given, and the most important and more frequently used methods for the synthesis of Fe 3 O 4 @C core-shell nanoparticles have been summarized along with the description of its adsorbent application potential.

“…So far, three main strategies have been widely used to improve the electrochemical performance of the transition metal oxide electrodes [22][23][24]: (I) Construction of mesoporous nanostructures, such as nanoparticles (NPs) [25], nanospheres [26], nanotubes [27] and nanosheets [28], in order to keep the absolute small volume changes and stabilize the dimensional integrity and the microstructure of the overall material during cycling. For example, Liu et al [29] synthesized the amorphous SnO2 nano-membranes as anodes for LIBs, which demonstrated a long cycling life of 1000 cycles at 1600 mA g −1 with a high reversible capacity of 854 mAh g −1 .…”

Graphical abstractHighlights  rGO-Fe3O4-SnO2-C quaternary hierarchical nanosheets were synthesized. Nano pores with an average size of 5.8 nm were fabricated within the nanosheets. rGO-Fe3O4-SnO2-C nanosheets exhibits excellent cycling performances. rGO-Fe3O4-SnO2-C anode displays low resistance and high structural stability. Abstract: A quaternary hierarchical nanocomposite, rGO-Fe3O4-SnO2-C, is rationally designed and synthesized via layer-by-layer constructions of reduced graphene oxide (rGO) flexible films, Fe3O4 nanoparticles, SnO2 nanoparticles and an omnidirectional amorphous carbon layer. SEM and TEM observations show that the Fe3O4 and SnO2 nanoparticles are uniformly dispersed on the rGO nanosheets and fully encapsulated by the outmost carbon layers, forming a sandwich-like buffering structure for excellent dimensional integrity. Furthermore, nanopores with an average size of 5.8 nm are fabricated within the quaternary hybrid nanosheets via a layer-by-layer packing of Fe3O4 and SnO2 nanoparticles, which possess the different shapes and sizes.Galvanostatic charge/discharge measurements demonstrate that rGO-Fe3O4-SnO2-C 1 exhibits a reversible capacity of 868.6 mAh g −1 after 100 cycles at a current density of 200 mA g −1 . Even at a current density of 2.0 A g −1 , it can be stably operated during the discharge/charge processes and deliver a reversible capacity of 414.7 mAh g −1 . The excellent electrochemical properties of rGO-Fe3O4-SnO2-C can be attributed to the microstructural stability of the hybrid and the synergistic effects of the components inside the nanosheets.
