“…The poor stability of zinc electrodes, due to the shape change and dendrite formation during the discharge-charge period, oen lead to poor cycling performance for conventional zincbased alkaline batteries. 11,20 The persistence of a conductive 3D copper foam substrate, which supports enhanced peak power density and specic capacity in primary zinc/oxygen battery, may also promote the rechargeability of Zn/Cu foam electrode. The control of the dissolution/precipitation process of zinc on copper foam substrate is signicantly important to avoid shape change and dendrite formation, and further improves the rechargeability of the zinc-based batteries.…”

Three-dimensional (3D) Zn/Cu foam electrodes are fabricated by pulse electro-deposition of zinc on copper foam and investigated as negative electrode materials for zinc-based alkaline batteries. Scanning electron microscopy (SEM) images show that epitaxially layered zinc crystals distribute uniformly on the 3D copper foam-like skeleton. A peak power density of 286 mW cm À2 and utilization of 92% (754 mA h g À1 at 200 mA cm À2 ) are obtained when the Zn/Cu foam electrodes are used in primary zinc/oxygen batteries and reveal high rate capability and material utilization of the 3D electrodes. To probe the rechargeability of the Zn/Cu foam electrodes, zinc/zinc quasi-symmetric cells are cycled under severe conditions, i.e., a discharge-charge current density of as high as 250 mA cm À2 , 100% depth of discharge and without dendrite-suppressing additives that would otherwise suppress dendrite growth, yet the 3D Zn/Cu foam electrodes remain dendrite-free experienced 10 000 discharge-charge cycles. The specific capacity of the 3D Zn/Cu foam electrodes reaches up to 620 mA h g À1 after at least 9000 discharge-charge cycles in a prototype Zn/Ni battery, exhibiting the superior cycling stability of the 3D Zn/Cu foam electrodes.

“…The divalent (MII) and trivalent (MIII) elements are arranged into nanolayers (0.48 nm) [27], and the positive charge of the nanolayers is neutralized by interlayer anions (A n-). According to the nanolayered structures of LDHs, they exhibited promising applications in many aspects, such as adsorbents [28], photocatalysts [29], anodic materials [30], sensors [31], magnetic materials [32], and energy conversion and storage [33]. The common factor in these studies was to look for a better control of the size and shape of LDH particles, producing more efficient products for the potential applications.…”

In this study, series of nanolayered structures of Zn-Al LDHs were prepared by urea hydrolysis. Nanofibers and nanonets of the Al-doped ZnO were formed via the decomposition of the nanolayers under high pressure and temperature. Nanospheres were also prepared for comparison. The different morphologies of the prepared nanomaterials were confirmed by several techniques. An improvement for the optical properties of the doped zinc oxides was observed through narrowing of their band gap energies because of transforming the nanolayers to nanonets and nanofibers. The photocatalytic activities of the prepared nanomaterials were studied through photocatalytic degradation of the pollutants of acid green dyes. Complete decolorization and mineralization of green dyes happened in the presence of the nanolayers and nanospheres within 4-6 h, while the nanonets and the nanofibers achieved the complete decolorization and degradation of the dyes at shorter time 1.3 h. These results could be explained though the kinetic study of the photocatalytic degradation of dyes. It was concluded that the nanonets and the nanofibers were very effective for the photocatalytic degradation of pollutants.Keywords Al-doped ZnO nanolayers Á Nanofibers Á Nanonets Á Band gap energy Á Photocatalytic degradation Á Acid green dyes pollutants

“…At present, some special layered hydroxide materials have been used in many aspects, including catalysts, ion conductivity, adsorbents, and anion exchange. 11 − 14 Moreover, hydroxides have good stability in alkaline solution, so there have been some research studies on the electrochemical performance of LDHs in alkaline secondary batteries. Some researchers have applied Zn–Al-LDHs to the zinc electrode of the zinc–nickel battery as a negative material.…”

Zn–Al–La layered double hydroxides (LDHs) were prepared by the hydrothermal method and used as a new anodic material for Zn–Ni secondary batteries. The morphology and microstructure of Zn–Al–La-LDHs were analyzed by Fourier transform infrared, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The electrochemical properties of Zn–Al–La-LDHs as negative electrode materials for Zn–Ni batteries were studied by the cyclic voltammetry, Tafel polarization curve, and constant current charge–discharge test. XRD and SEM analysis showed that the crystallinity of the prepared Zn–Al–La-LDHs was good and the dispersion was uniform and showed regular hexagonal structures. The results of electrical properties show that Zn–Al–La-LDHs have good cycle reversibility and corrosion resistance when applied to Zn–Ni secondary batteries. The analysis of galvanostatic charge–discharge measurement results shows that the Zn–Al–La-LDH electrode has excellent cycle stability and charge–discharge characteristics. After 150 cycles, the cycle retention rate can reach 91.63%.
