“…However, the shapes of these CV curves don't show apparent differences, indicating their good electrochemical reversibility and stability. In addition, the redox peak currents are clearly increased with the increase of scan rates, which indicates the redox reactions at the interfaces between the CeO2-Zr-1 electrode and KOH electrolyte are much faster and more efficient during charge/discharge processes [60]. The electrodes using CeO2, CeO2-Zr-0.5 and CeO2-Zr-1.5 all exhibit the similar results as shown in Fig.…”

“…In fact, it has been demonstrated that NiO and Ni(OH) 2 -based nanostructures possess superior electrochemical properties due to their high surface to volume ratio, efficient electrolyte penetration and low resistance 7 . Over the past years, 0D (nanoparticles 8 ), 1D (nanowires 9 ), 2D (nanosheets 10 ) and 3D (flower-like structure 11 , nanowalls 12 ) nanostructures have been developed. Among them, 3D materials are the more advantageous ones, since their better connectivity results in higher electrical conductivity and improved mechanical stability 13 .…”

Energy storage performances of Ni-based electrodes rely mainly on the peculiar nanomaterial design. In this work, a novel and low-cost approach to fabricate a promising core-shell battery-like electrode is presented. Ni(OH) 2 @Ni core-shell nanochains were obtained by an electrochemical oxidation of a 3D nanoporous Ni film grown by chemical bath deposition and thermal annealing. This innovative nanostructure demonstrated remarkable charge storage ability in terms of capacity (237 mAh g −1 at 1 A g −1 ) and rate capability (76% at 16 A g −1 , 32% at 64 A g −1 ). The relationships between electrochemical properties and core-shell architecture were investigated and modelled. The high-conductivity Ni core provides low electrode resistance and excellent electron transport from Ni(OH) 2 shell to the current collector, resulting in improved capacity and rate capability. The reported preparation method and unique electrochemical behaviour of Ni(OH) 2 @Ni core-shell nanochains show potential in many field, including hybrid supercapacitors, batteries, electrochemical (bio)sensing, gas sensing and photocatalysis.

“…The band gap value Eg of hydrangea-like ZnS/ZnIn 2 S 4 microspheres is 2.08 eV for the indirect band gap by measuring the x-axis intercept of an extrapolated line from the linear region of the curve in Figure 5(b). The low band gap of ZnS/ZnIn 2 S 4 may be caused by the combined action of zinc element and indium element and the large specific surface area of hydrangea-like ZnS/ZnIn 2 S 4 microspheres where it is easier for electrons to be excited from VB to CB [7,29].…”

“…However, the band gap of TiO 2 is as large as 3.2 eV [6]. Also, the spectral absorption range is narrow for which photogenerated electrons (e − ) and holes (h + ) are easy to recombine, reducing its catalytic performance [7,8]. Therefore, it's desirable to engineer a new photocatalyst with a narrow band gap.…”

By hydrothermal reaction, the hydrangea-like ZnS/ZnIn 2 S 4 microspheres were prepared in the presence of thioacetamide. X-ray photoelectron spectroscopy and high resolution transmission electron microscopy confirmed that the ultra-long nanowires are composed of ZnS and ZnIn 2 S 4 . Scanning electron microscopy showed the morphology of ultra-thin nanosheets with an average thickness of 8.5 nm cross from inside to outside, forming ZnS/ZnIn 2 S 4 microspheres with a porous diameter of about 2.8 μm. Nitrogen adsorption desorption isotherm determined that the BET specific surface area of the microspheres was 109.19 m 2 /g which showed that they have a large specific surface area. The obtained ZnS/ZnIn 2 S 4 microspheres showed broad absorbance ranging from UV (200 nm) to visible (520 nm) with low indirect band gaps of 2.08 eV. It leads to outstanding visible-lightdriven photocatalysis for the degradation of xylenol orange (XO) and thymol blue (TB) in water, and the two dyes were almost completely degraded after 60 and 135 min, respectively. This provides new potential to explore nanomaterials for efficient photo-driven degradation of organic dyes under visible light irradiation.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
