“…To further understand the excellent catalytic activity of monolayer NiV LDH nanosheets, the mechanism for water oxidation using density functional theory (DFT) calculation was investigated (Figure 1C). DFT results demonstrate that the incorporation of vanadium in Ni(OH) 2 nanosheets facilitates the formation and adsorption of OOH* (Figure 1Ce), indicating that NiV LDH nanosheets have a higher catalytic activity for water oxidation 63. These excellent catalytic properties can be mainly attributed to the increase in some active sites and the improvement of intrinsic catalytic activity of active sites 63…”

“…In this study, the unique monolayer NiV LDH nanosheets with high specific surface area facilitate the exposure of more active sites 63. The incorporation of vanadium is also helpful to improve the electrical conductivity of Ni(OH) 2 and decreases the charge transfer resistance in OER process 63. The monolayer of NiV LDH nanosheets as OER electrocatalysts exhibits a high current density of 57 mA cm −2 at an overpotential of 350 mV for OER which was superior to NiFe LDH electrocatalysts for water oxidation (Figure 1B).…”

Recent Progress on Layered Double Hydroxides and Their Derivatives for Electrocatalytic Water Splitting

Layered double hydroxide (LDH)‐based materials have attracted widespread attention in various applications due to their unique layered structure with high specific surface area and unique electron distribution, resulting in a good electrocatalytic performance. Moreover, the existence of multiple metal cations invests a flexible tunability in the host layers; the unique intercalation characteristics lead to flexible ion exchange and exfoliation. Thus, their electrocatalytic performance can be tuned by regulating the morphology, composition, intercalation ion, and exfoliation. However, the poor conductivity limits their electrocatalytic performance, which therefore has motivated researchers to combine them with conductive materials to improve their electrocatalytic performance. Another factor hampering their electrocatalytic activity is their large lateral size and the bulk thickness of LDHs. Introducing defects and tuning electronic structure in LDH‐based materials are considered to be effective strategies to increase the number of active sites and enhance their intrinsic activity. Given the unique advantages of LDH‐based materials, their derivatives have been also used as advanced electrocatalysts for water splitting. Here, recent progress on LDHs and their derivatives as advanced electrocatalysts for water splitting is summarized, current strategies for their designing are proposed, and significant challenges and perspectives of LDHs are discussed.

“…These values are also higher than those of the plain NiO electrode (265, 189, and 73 F g −1 at the scan rates of 10, 20, and 50 mV s −1 , respectively). Quantitative analysis of the electrochemically active surface area (ECSA) on the electrodes was also conducted 19. Figure S7 (Supporting Information) shows the cyclic voltammograms of both electrodes obtained at different scan rates (5–50 mV s −1 ) in the potential range of 0–0.1 V, where no Faradaic reaction occurred.…”

Nanoporous Films and Nanostructure Arrays Created by Selective Dissolution of Water‐Soluble Materials

et al. 2018

Highly porous thin films and nanostructure arrays are created by a simple process of selective dissolution of a water‐soluble material, Sr3Al2O6. Heteroepitaxial nanocomposite films with self‐separated phases of a target material and Sr3Al2O6 are first prepared by physical vapor deposition. NiO, ZnO, and Ni1− xMgxO are used as the target materials. Only the Sr3Al2O6 phase in each nanocomposite film is selectively dissolved by dipping the film in water for 30 s at room temperature. This gentle and fast method minimizes damage to the remaining target materials and side reactions that can generate impurity phases. The morphologies and dimensions of the pores and nanostructures are controlled by the relative wettability of the separated phases on the growth substrates. The supercapacitor properties of the porous NiO films are enhanced compared to plain NiO films. The method can also be used to prepare porous films or nanostructure arrays of other oxides, metals, chalcogenides, and nitrides, as well as films or nanostructures with single‐crystalline, polycrystalline, or amorphous nature.
