“…The Zn 2p XPS spectrum (Figure 6B) presents the doublet peaks located at binding energies of 1045.6 eV and 1022.6eV, which corresponds to Zn 2p 1/2 and Zn 2p 3/2 , respectively (Li W. Q. et al, 2015). The result indicates that the Zn 2+ is the dominant species in the prepared material and in good agreement with the reported data for ZnO (Zhao et al, 2015). Figure 6C shows the binding energy of Sn 3d 5/2 , Sn 3d 3/2 are 487.6eV and 496.1eV respectively, which are assigned to the highest oxidation state of Sn 4+ for SnO 2 (Hamrouni et al, 2014; Chen et al, 2018).…”

Hydrogen sulfide (H2S) is an important decomposition component of sulfur hexafluoride (SF6), which has been extensively used in gas-insulated switchgear (GIS) power equipment as insulating and arc-quenching medium. In this work, electrospun ZnO-SnO2 composite nanofibers as a promising sensing material for SF6 decomposition component H2S were proposed and prepared. The crystal structure and morphology of the electrospun ZnO-SnO2 samples were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), respectively. The composition of the sensitive materials was analyzed by energy dispersive X-ray spectrometers (EDS) and X-ray photoelectron spectroscopy (XPS). Side heated sensors were fabricated with the electrospun ZnO-SnO2 nanofibers and the gas sensing behaviors to H2S gas were systematically investigated. The proposed ZnO–SnO2 composite nanofibers sensor showed lower optimal operating temperature, enhanced sensing response, quick response/recovery time and good long-term stability against H2S. The measured optimal operating temperature of the ZnO–SnO2 nanofibers sensor to 50 ppm H2S gas was about 250°C with a response of 66.23, which was 6 times larger than pure SnO2 nanofibers sensor. The detection limit of the fabricated ZnO–SnO2 nanofibers sensor toward H2S gas can be as low as 0.5 ppm. Finally, a plausible sensing mechanism for the proposed ZnO–SnO2 composite nanofibers sensor to H2S was also discussed.

“…In this work, graphene layers acted as a buffer and mechanical support to prevent volume increase, along with mechanical disintegration of the anode structure and supplied high electronic conductivity with its outstanding electronic, mechanic, and porous nature. Furthermore, the composite of ZnO‐SnO 2 contributed to improve anode capacity through useful synergistic effects as mentioned above . It can be concluded from these results that we achieved our goal for further Li‐ion battery applications with beneficial outcomes.…”

Summary Free‐standing, flexible, and binderless binary ZnO‐reduced graphene oxide (rGO), SnO2‐rGO, and ternary ZnO‐SnO2‐rGO Li‐ion anodes were produced by vacuum filtrating the mixture of metal oxides synthesized by sol‐gel method and graphene oxide produced by Hummers method. These paper anodes were designed by being decorated with metal oxides between rGO layers. To compare nanocomposite anode structures, field emission gun‐scanning electron microscopy, energy dispersive X‐ray spectrometer, X‐ray diffraction, and electrochemical analyses were applied. The results suggested that ternary ZnO‐SnO2‐rGO paper anode exhibited larger discharge capacity and capacity retention than the binary anodes even after 100 cycles. This finding is attributed to buffering effect of rGO on volume expansion of the anode structure designed by sandwich‐type production and the synergic effect of ZnO‐SnO2 oxides.

Electrospinning has attracted tremendous attention in the design and preparation of 1D nanostructured electrode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (NIBs), due to the versatility and facility. In this review, we present a comprehensive summary of the development of electrospun electrode nanomaterials for LIBs and NIBs, and a brief introduction about electrode materials beyond LIBs and NIBs. By summarizing various electrochemical active materials, this review focuses on the evolution in structures and the constitution of electrospun electrode materials. In detail, a variety of electrospun anode and cathode materials of LIBs and NIBs have been properly discussed, respectively. Finally, the current progress in the electrospun electrode materials is well reviewed and the development direction is also pointed out. We believe that in the nearly future, electrospun electrode materials would be applied in commercial LIBs and promote the advance in NIBs. And we hope that this review could be helpful in the design and fabrication of electrospun hierarchical materials for other advanced energy-storage devices.
