“…1A shows the XRD patterns of different samples during the preparation process of FeC x /NCNFs and the relevant electrochemical activity in DMA degradation. When the prepared polymer fibers were stabilized in air at 280 C for 2 h, all peaks could be assigned to the phase pure rhombohedral Fe 2 O 3 (JCPDS Card No.33-0664) (Chen et al, 2015), while in the carbonization process, the three most probable phases (Fe 7 C 3 , Fe 3 C and a-Fe) were considered, which have positions around 2q~45 for the most intense maxima. The Fe 7 C 3 phase with 00-017-0333 JCPDS code has distinct peaks at 2q ¼ 50.5 and 53.2 attributed to (202) and (220) crystallographic planes.…”

“…The combination of TiO2 with Fe2O3 to form a core-shell structured nanocomposite can decrease the recombination rate of photogenerated electrons and holes. Moreover, the core-shell structured Fe2O3@TiO2 nano-composites can be used to improve the visible light response of TiO2 [17,18].…”

Abstract.A new synthetic approach has been developed to prepare α-Fe2O3@TiO2 core-shell nanostructures at ambient conditions (e.g., in water, ≤100 °C). This approach shows a few unique features, including: short reaction time (a few minutes) for forming core-shell nanostructures, no requirement of high temperature calcinations for generating TiO2 (e.g., at 80-100 °C), tunable TiO2 shell thickness, high yield and good reproducibility. The experimental results show that the α-Fe2O3@TiO2 core-shell nanostructures exhibit enhanced photocatalytic activity compared to the pure TiO2 (P25) and pure Fe2O3 in degradation of organic dye molecules with visible light irradiation. This could be attributed to the large surface area of TiO2 nanoparticles for maximum adsorption of dye molecules, and the effective charge separation at the heterojunction of α-Fe2O3 and TiO2. The findings may open a new strategy to synthesize TiO2-based photocatalysts with enhanced efficiency for environmental remediation applications.

As the energy crisis turning out to be more and more serious, an interest in renewable energy sources is also increasing. [3] Researchers around the world have been devoting themselves to developing a high-performance electric energy storage material [4] to meet the demand for ecofriendly, sustainable, and low-cost energy. Among several kinds of electrical energy storage systems, lithiumion batteries have been developed as largescale energy storage units [5] and energy storage medium in electric vehicles, [6] smart grids, and other clean energy systems such as solar and wind since 1990s. [7] The lithium ion battery is identified as one of the ideal candidates to meet these requirements due to its desired energy density, superior voltage, and light weight. [8] However, extensive application of lithium ion batteries faces challenges related to the availability and cost of lithium. Scientists have their eyes on making sodium ion batteries as an alternative, because sodium is more abundant than lithium. Except that, it is also cheaper and easy to recover. [9] So nowadays, studying new kinds of electrode materials for lithium ion batteries and sodium ion batteries can be a rewarding work.During the last few decades, LiFePO 4 has attracted much attention, which was reported as a positive electrode for rechargeable lithium ion batteries first by Good-enough and co-workers in 1990s. [10] Nowadays, thousands of research publications have been authored on LiFePO 4 , [11] such as graphene-encapsulated LiFePO 4 composite, [12] pure LiFePO 4 , and LiFePO 4 /C, [13] 3D porous LiFePO 4 , [14] olivine LiFePO 4 , [15] mesoporous carboncoated LiFePO 4 , [16] graphene-modified LiFePO 4 , [17] LiFePO 4 / reduced graphene oxide hybrid, [18] and so on. LiFePO 4 owns favorable kinetics of the lithium intercalation/deintercalation process [19,20] and its nanocrystal size and shape can be easily controlled, [21] especially when it is complexed with carbon-based materials or other elements, the electrochemical properties of the composite material can be greatly improved. [22,23] It also has advantages of atop safety, environmental friendliness, affordability, as well as its comparatively reasonable electrochemical performance. [24][25][26][27] Until now, many researchers have examined LiFePO 4 as next generation cathode material. [28] Since FePO 4 also shows intrinsically poor ionic and electrical conductivity, small tap density which influences its electrochemical performance, [29] LiFePO 4 will not be further discussed in this article.High-performance electric energy storage material has recently developed due to the attention for sustainable development. As ecofriendly energy storage device, lithium ion batteries and sodium ion batteries deserve more concern today. FePO 4 and NaFePO 4 share similar advantages such as easy preparation, abundant, and inexpensive, so they can be ideal materials for lithium/sodium ion batteries. This review is focused on recent progresses in nanostructured FePO 4 /NaFePO 4 -based nanomaterial as cathode ma...
