“…The discharge/charge voltage profiles and corresponding d Q /d V curves of the 3D FNN and 3D HD‐FMN electrodes for the 1st, 50th, 100th, and 200th cycles at a current rate of 0.1 C (1 C = 1 A g −1 ) are plotted and presented in Figure S7 (Supporting Information) and Figure . As shown in the 3D FNN electrode, the distinct voltage plateaus/reduction peaks at 0.73 and 0.86 V can be observed during the first cycle (Figure S7b,c, Supporting Information), which is consistent with the previously reported studies, referring to the occurrence of side reactions on the electrode surface and interface due to formation of SEI film, as well as the electrochemical reaction between Fe 3 O 4 nanosheets and lithium ions. In the d Q /d V curves, an obvious oxidization peak at ≈1.6 V can be assigned to the oxidation of Fe to Fe 3 O 4 (Figure S7c, Supporting Information).…”

“…However, metal oxide particles tend to agglomerate and the electrode undergoes an obvious volume change when hosting or releasing lithium ions, leading to the electrode pulverization and the capacity degradation . To overcome these drawbacks, various strategies have been carried out to improve the specific capacity and structural integrity of Fe 3 O 4 ‐based anodes, that is preparing the Fe 3 O 4 materials with diverse microstructures and nanostructures or coupling the carbon materials in Fe 3 O 4 . Up to now, a large number of Fe 3 O 4 /carbon composites have been synthesized and evaluated as effective LIB anodes, such as carbon‐encapsulated Fe 3 O 4 , carbon‐coated Fe 3 O 4 , Fe 3 O 4 ‐decorated graphene, graphene‐wrapped Fe 3 O 4 , Fe 3 O 4 ‐embedded in carbon matrix, and Fe 3 O 4 /carbon nanotubes .…”

Owing to unique lamellar nanostructures, 2D inorganic materials are considered as promising candidates in energy storage and conversion. In this paper, a facile two‐step synthesis is developed to fabricate 3D hierarchical dual Fe3O4/MoS2 nanosheets (HD‐FMNs), in which few‐layered MoS2 nanosheets are anchored in 3D Fe3O4 nanosheet network to form the heterojunction structure. Furthermore, it is proved that the synergistic effects on both electron/lithium‐ion transport kinetics and mechanical cycling stability benefit from Fe3O4/MoS2 nanosheet incorporation in 3D HD‐FMN anode for lithium‐ion batteries (LIBs), resulting in the dramatically enhanced performance. The Fe3O4 nanosheet incorporation effectively improves the electronic conductivity due to its half‐metal characteristic, while the defect‐rich structure in the MoS2 nanosheets can facilitate the lithium ion transport. When tested as potential anode materials, 3D HD‐FMNs exhibit a high reversible capacity (650 mAh g−1) at current rate of 5 C (1 C = 1 A g−1) after superior long‐term cycles (1000 times), as well as an excellent rate capability even at high current rates. The outstanding electrochemical property of 3D HD‐FMNs allows their application in high‐performance anode materials for next‐generation LIBs. This strategy also opens a new way to design the novel 2D composite materials for electrochemical devices.

We report a facile method to synthesize magnetite nanoparticles with mesoporous structure by coprecipitation method using different stabilizing agents like salicylic acid, glutamic acid, and trichloroacetic acid. The stabilizing agents were used to prevent the aggregation of the magnetite nanocrystals and to obtain stable nanostructures even in the biological environment. The structure and morphology of magnetic nanocrystals were determined using X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, Brunauer-Emmett-Teller (BET) analysis, infrared (IR) spectra, scanning and transmission electron microscopy (SEM and TEM), high-resolution transmission electron microscopy (HRTEM), and selected area electron diffraction (SAED). The results reveal important differences between these magnetic nanoparticles (MNPs), which are mainly attributed to the stabilizing agents. The smallest nanoparticles were obtained in the presence of trichloroacetate ions. The mechanism of formation of these suprastructures is strongly correlated with the end functional groups of the stabilizing agent. Thus, the obtained nanoparticles are potential candidates for contrast agents as well as targeted carrier for specific diseases, especially cancer.

“…The co-precipitation method involves the mixing of Fe 2+ and Fe 3+ in 1:2 proportion, precipitation under alkali conditions followed by filtering, washing and drying to generate Nano-Fe 3 O 4 . Due to its simple procedure, low cost and rapid reaction co-precipitation methods have been widely used [27,28], (see Figure 2). Qin et al [29] adopted the chemical coprecipitation method, taking NH 3 ·H 2 O as the precipitant, which was added to a mixed solution of Fe 2+ and Fe 3+ .…”

Ferroferric oxide nanoparticle (denoted as Nano-Fe 3 O 4 ) has low toxicity and is biocompatible, with a small particle size and a relatively high surface area. It has a wide range of applications in many fields such as biology, chemistry, environmental science and medicine. Because of its superparamagnetic properties, easy modification and function, it has become an important material for addressing a number of specific tasks. For example, it includes targeted drug delivery nuclear magnetic resonance (NMR) imaging in biomedical applications and in environmental remediation of pollutants. Few articles describe the preparation and modification of Nano-Fe 3 O 4 in detail. We present an evaluation of preparation methodologies, as the quality of material produced plays an important role in its successful application. For example, with modification of Nano-Fe 3 O 4 , the surface activation energy is reduced and good dispersion is obtained.
