Summary Carbon nanofiber film (CNF) as anode material for lithium‐ion batteries (LIBs) draws attention for its excellent cyclic stability, but its practical application is limited due to low specific capacity. Considering the advantages of pure CNF and MoS2, a flexible film which CNF covered by MoS2 (MoS2/CNF) is successfully produced and evaluated as a binder‐free electrode for LIBs without mixing with carbon black and polymer binder. MoS2 nanoflakes (8.91 wt% of the composite sample) covering on CNF (MoS2/CNF‐B sample) plays the key role in activating the electrochemical properties of CNF, but dense MoS2 nanoflakes (39.4 wt%) on CNF (MoS2/CNF‐A) seriously limit the electrochemical properties of CNF. At 0.1 and 1.0 A g−1, MoS2/CNF‐B sample delivers 967.1 and 605.7 mA h g−1, the capacities are almost twice as much as those of pure CNF. The initial columbic efficiency of MoS2/CNF‐B sample of 76.4% is much higher than that of pure CNF sample of 62.1%. Moreover, MoS2/CNF‐B sample presents no capacity decay till 100 cycles, and the cycled electrode at the 100th cycle still maintains a stable composite structure of MoS2 nanoflakes covering on CNF.

Over the past few decades, ambient air pollution (AAP) sources, including exhaust fumes, toxic air, and particulate materials (PMs), have increased due to power generation, vehicle emissions, and the gas industry. This has compromised environmental safety. In 2018, the World Health Organization (WHO) reported the effects of AAP and household air pollution (HAP) on human health. According to these reports, outdoor air pollution has not only gradually changed our living habits, but also increased the probability of death and diseases, including lung cancer, strokes, ischemic heart disease, and acute respiratory infections. Another report from the WHO in 2016 mentioned that AAP and HAP had caused the death of 543 000 children under the age of 5 years. [1,2] These reports indicate a direct link between AAP, HAP, and human health. HAP includes volatile organic compounds, PMs, CO, SO 2 , and NO. Cooking, heating, and burning solid or liquid fuels such as wood, coal, kerosene, and gasoline generate large amounts of pollutants, which strongly impact human health, especially that of young children and people who spend majority of their time indoors. According to the Occupational Safety and Health Administration (OSHA) regulations of the United States Department of Labor, the concentrations of CO and NO gas in a workplace should not exceed 35-50 ppm and 30-45 ppm, respectively. CO and NO, which are colorless, tasteless, and have nonirritant properties, [3-7] are toxic gases. If people are exposed to a CO and NO gas environment for a long time, these gases dissociate into their blood and combine with hemoglobin (Hb) to reduce the oxygen-carrying capacity of the blood. Hence, it is important to prevent or minimize HAP. To reduce AAP and HAP (CO, SO 2 ,and NO x), semiconductor materials (ZnO, TiO 2 , and SnO 2) could be converted into high porosity polycrystalline nanofibers (PNFs), which have many advantages, including a nanointerface between nanograins, [8,9] wide band gap (3.6 eV), and generation-recombination centers, owing to the defects and dangling bonds at the end of nanograin's surface. Recent studies on the development and application of PNFs suggest that they can be used in photonic devices, such as photon sensors [10-13] and solar cells, [14,15] as well as non-photonic devices, such as PM filters, [16,17] toxic gas sensors, [18-34] biological sensors, [35-39] RRAM devices, [40,41] and energy devices. [42-49] The indoor ambient temperature for the majority of households is ≈25-30 °C. According to Yang and co-workers [50] and Moon et al., [29] SnO 2 and TiO 2 The development of SnO 2 and TiO 2 polycrystalline nanofiber devices (PNFDs) has been widely researched as a method of protecting humans from household air pollution. PNFDs have three significant advantages. The nanofibers before the annealing process are polymer-rich materials, which can be used as particulate material (PM) filters. The multiporous nanofibers fabricated by the annealing process have numerous defects that can serve as generation-recombination c...

“…Therefore, it is essential to develop new anode materials with high specific capacities. Nanomaterials of metal oxides, such as SnO 2 , Co 3 O 4 , Fe 2 O 3 , Mn 3 O 4 , and NiO, [10–14] have been widely investigated as probable high‐energy anode materials for LIBs. Among these potential candidates, Fe 2 O 3 is considered the most promising, owing to its high specific capacity (1007 mAh g −1 ), non‐toxicity, low cost, and abundant natural availability.…”

The use of inexpensive graphite oxide (GO) as a carbon source, instead of the expensive reduced graphene oxide (rGO), is essential to prepare metal oxide/rGO composites. In this work, we investigated the in situ reaction of GO and FeCl3 to produce Fe2O3/rGO composites as anode materials for high‐energy lithium‐ion batteries (LIBs). In this reaction, iron ions combined with the oxygen‐containing functional groups of GO, which subsequently grew into Fe2O3 nanoparticles, whereas the GO transformed into rGO under hydrothermal conditions. In the composite Fe2O3−rGOx samples, intergranular gaps in the Fe2O3 sub‐micron particles evidently increased the contact between the Fe2O3 active material and the electrolyte, which improved the Li‐ion conductivity and electrochemical performance of the Fe2O3−rGOx composites. The Fe2O3−rGO2 sample showed the best cyclic performance and delivered the highest capacity of all samples. The initial discharge and charge capacities of Fe2O3−rGO2 were 1086.3 and 722.4 mAh g−1, respectively. After 100 cycles, the discharge specific capacity of Fe2O3−rGO2 was 653.2 mAh g−1 and the coulombic efficiency was 98.4 %. We found that an appropriate weight ratio and composite morphology of Fe2O3−rGOx were important in influencing the electrochemical properties of the composite anode materials for high‐energy LIBs.
