“…Two strong peaks located at 1345 cm −1 (D-band) and 1595 cm −1 (G-band) are observed in the spectrum of Ni microtube/CNSs CSAs, indicating the presence of carbon ( Figure 3 a). [ 36 ] The phase change of products is also verifi ed by the XRD analysis (Figure 3 b). The characteristic peaks of hexagonal ZnO phase (JCPDS 36-1451) are clearly seen in the samples after the CBD and ED but vanish after the HS growth of carbon spheres.…”

than batteries.[ 3 ] As a result, EDLCs have become a promising power solution and alternative to batteries for a wide spectrum of applications. To date, carbon materials are the prevailing active materials for EDLCs due to excellent cycling life, high power density, fast charge/discharge capability, and low cost. [ 4,5 ] Design and fabrication of advanced carbon materials with high power/energy density have been the research focus of EDLCs.Carbon nanomaterials have a unique place in nanoscience due to their interesting and exceptional chemical, mechanical, and electrical properties, and have been widely used in different areas, particularly in energy storage and conversion devices. [ 6,7 ] The family of carbon nanomaterials includes carbon nanotubes, fullerenes, graphene, and carbon nanospheres (CNSs). In recent years, in parallel with the intensive research on CNTs and graphene, [ 6,[8][9][10][11][12][13] CNSs continue to gain attention and renewed efforts with signifi cant advance in the fi eld of catalysis, [ 14,15 ] and electrochemical energy storage such as Li-ion batteries and supercapacitors. [ 16 ] CNSs can not only be directly used as the active materials of electrodes for batteries and supercapacitors [17][18][19][20] but also have been widely employed as the scaffold/template to prepare spherical composites with metal (Pt, Ru, Cu, etc.), [21][22][23] sulfur, [ 24 ] and metal oxides (such as TiO 2 / CNSs, [ 25 ] SnO 2 /CNSs, [ 26 ] MnO 2 /CNSs, [ 27 ] MoO 2 /CNSs, [ 28 ] ZnO/ CNSs, [ 29 ] Co 3 O 4 /CNSs, [ 30 ] and Fe 2 O 3 /CNSs [ 31 ] ). Improved functional properties have been demonstrated in most of these twocomponent systems. However, to date, all the above research is focused on powder materials, regardless that the CNSs are prepared by template methods or template-free methods. Oriented array structures of CNSs have not been reported yet. Different from carbon nanotubes, CNSs are much more diffi cult to be directionally assembled into self-supported arrays. Therefore, in electrochemical storage and electrocatalysis applications, it is highly desirable and essential to develop powerful and cheap strategies for the rational synthesis of micro/nanoarrays of CNSs-based composites.Here, we report self-supported metal (Ni and Co) microtube/ CNSs core/shell arrays (CSAs) on conductive substrates by three-step all solution-based methods. Full characterization and supercapacitor demonstration are made to Ni microtube/CNSsThe high performance of electrochemical energy-storage devices relies largely on scrupulous design of nanoarchitectures and smart hybridization of bespoke active materials. Carbon nanopsheres (CNSs) are widely used for energy storage and conversion devices. Here, the directional assembly of CNSs on a vertical-standing metal scaffold into a core/shell array structure is reported. The method uses a three-step all-solution synthesis strategy (chemical bath deposition, electrodeposition, and hydrothermal) and begins from ZnO microrod arrays as a sacrifi cial template. The self-assembly of CN...

“…Among which, higher theoretical capacity of 978 mAh/g than graphite (372 mAh/g) and similar bandgap (3.37 eV) with TiO 2 (theoretical capacity is 335 mAh/g), Zinc oxide (ZnO) has already attracted a great deal of interest of researchers to study its performance in LIBs and DSSC [19][20][21]. However, as an anode for LIBs, nanostructured ZnO electrode suffer from the low electronic conductivity and the loss of electrical contact arising from the volume expansion during the charge-discharge process which result in capacity degradation and poor cycling performance [22,23]. Besides, nanostructured ZnO-based DSSCs exhibit low cell efficiencies than TiO 2 nanoparticle-based DSSCs, mainly due to the recombination of injected electrons [24].…”

“…Herein, we successfully fabricated three dimensional ZnO nanostructures by growing ZnO nanoparticles on flexible carbon cloth with high conductivity, and it was directly used as the integrated binder-free electrode for LIBs, which delivered superior electrochemical properties including high specific capacity of 600 mAh/g, excellent stability up to 130 cycles without significant capacity declining fading compared to previous reported [22,25]. The excellent electrochemical performance can be attributed to the enhanced electron transport, shortened ion diffusion path, and the enhanced electro-active surface of the active materials.…”

Close packed ZnO nanoparticles on carbon cloth were synthesized by repeating a facile hydrothermal route in this study. After characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), the obtained ZnO cloth was further studied for the applications in lithium (Li)-ion batteries (LIBs) and dye-sensitized solar cells (DSSCs). When ZnO cloth annealed at 400°C for 2 h were used as anodes of LIBs, it exhibited high capacity of 600 mAh/g and outstanding cycling capability without significant fading after 130 cycles. Moreover, it was also found that our electrodes displayed good stabilities under various humidity and temperature. Furthermore, the obtained composites were calcined at higher temperature (800°C) to remove carbon and white pure ZnO cloth was formed. We transferred the as-formed ZnO cloth to fluorine-doped tin oxide (FTO) substrate to make DSSCs, exhibiting an improved efficiency of around 0.38% assisted by TiCl 4 treatment.

“…Zinc oxide has attracted extensive interest because of its important role in various applications, for example, gas sensor [2], surface acoustic wave devices [3], optical waveguides [4] as well as blue/UV light emitting devices [5]. Compared to other kinds of nanostructured lms, the ZnO lms have the advantages of structural versatility, easy fabrication and availability, which make them ideal templates for nanostructure construction [6,7]. ZnO lms can be deposited by a variety of techniques, such as solgel technique [8], spray pyrolysis [9], metal organic chemical vapor deposition [10], molecular beam epitaxy [11], pulsed laser deposition [12] and sputtering [13].…”

In this work, the eect of rf power on the structural, electrical and electrochemical properties of ZnO thin lms was investigated. ZnO thin lms were deposited on glass and Cr coated stainless steel substrates by rf magnetron sputtering in pure Ar gas environment. ZnO thin lms for dierent rf powers (75, 100, and 125 W) were deposited keeping all other deposition parameters xed. ZnO thin lms were used as negative electrode materials for lithium-ion batteries, whose charge-discharge properties, cyclic voltammetry and cycle performance were examined. A high initial discharge capacity about 908 mAh g −1 was observed at a 0.5 C rate between 0.05 and 2.5 V. The crystallographic structure of the sample was determined by X-ray diraction. The electrical resistivity of the deposited lms was measured by the four-point-probe method. The thickness of the ZnO thin lms was measured using a prolometer.
