“…In some recent studies, LDH films have been prepared in situ on magnesium [8][9][10][11][12] and aluminum alloys [13][14][15] for the purpose of corrosion protection. The metallic substrate is immersed in a suitable solution, and the film uses the metal substrate as internal source of metal cations to crystallize.…”

“…The orientation of the aromatic carbon ring in three-dimensional arrangement could be determined by the reflection of plane (002) [19,20] [1,21], indicating that the nanolayered structure of LDHs was successfully prepared. The basal spacing d-value of the (003) peak is 0.76 nm, which referred to the intercalation of carbonate into the interlayer spacing of LDHs [22][23][24]. The unit cell parameters (a and c) can be obtained from a = 2d(110) and c = 3d(003); respectively.…”

The current study aims at combining two building blocks together into well-designed nanostructures to act as dual-function materials; active photocatalysts in sunlight and effective adsorbents for increasing the efficiency of water purification. By these nanostructures, we could avoid the drawbacks of the existing technologies for water purification and remove the industrial pollutants by a dual process; adsorption and photocatalytic degradation. In this trend, Zn-Al layered double hydroxides (LDHs) are combined with graphene oxide to produce a series of nanolayered structures. These nanolayered structures are effective for converting Zn-Al LDHs to be photo-active in sunlight through decreasing its band gap energy from 5.5 eV to 2.5 eV. In addition, these nanolayered structures caused complete decolorization and mineralization of green dyes in sunlight through accelerating the reaction rate of the photocatalytic degradation of dyes seven times higher than that of the pure Zn-Al LDHs. In the same time, they improved the adsorption process of green dyes through creating new micro- and meso-porous structures and high surface area for Zn-Al LDHs. Finally, the well-designed nanostructures between Zn-Al LDHs and graphene oxide led to converting non-photoactive materials to be active in the visible light in addition to a complete and fast removal for organic pollutants.

“…This incorporate the urea technique, coprecipitation, ion exchange process and microwave light technique. Every synthesising methods have its own particular novel advantages and limitations when compared with alternate techniques [4]. The co-precipitation technique is the easiest and most regularly utilized of all techniques for the synthesis of LDHs.…”

“…A Zn-Al LDH was researched as an adsorbent material for the removal of iodide and iodine from water. Researchers was found that LDH can be used as a good adsorbent material which can expel the greater part of the iodine present in the test arrangements [4]. Once more, the items were portrayed by Evolved Gas Mass Spectrometry (EGMS), TGA and XRD trying to get it the removal of iodine.…”

Abstract. The layered double hydroxides (LDH) which are anionic clay substances comprising of stacked cationic layers and interlayer anions. The cationic sheets contain octahedral structure consisting the divalent and trivalent ions in the center and hydroxyl bunches in the corners, gathered by three bonding with the neighbouring octahedra on every side of the layer. The ratio between the quantity of cations and OH − ions is 2:1, so a positive charge shows up on the layer because of the presence of trivalent cations. The interlayer space gives the compensation anions and water molecules, assuring a balanced out layered structure. The LDH materials were successfully synthesised from magnesium, aluminium, zinc and chromium chloride salts utilizing the co-precipitation technique. A Zn-Al LDH was researched as a potential sorbent material. This article reviews the recent advances in the preparation and intercalation of layered double hydroxides and its application in the fabrication of Dye Sensitized Solar Cell (DSSC).
