Layered Double Hydroxide (LDH) is an α‐modification of the M‐host (M2+) hydroxide, in which some part of the M‐host cations is replaced by M‐guest cations (M3+ or M4+). The emerging excess positive charge is compensated by the intercalation of anions into the interlayer space, which also contains water molecules. LDHs exhibit anion exchange properties. Targeted ionic design of LDHs via combining three components (M‐host, M‐guest cations, intercalated anions) allows the creation of a very wide range of highly efficient electrochemical, electrocatalytic, electrochromic substances, catalysts, ion exchangers, sorbents, color pigments, pharmacological drugs, food, and cosmetic additives. In this review, the structure and areas of application of LDHs are considered from the perspective of the targeted ionic design of a substance for a specific application.

IntroductionLayered double hydroxides (LDHs) are widely studied anionite clays consisting of positively‐charged hydroxide nanosheets which is described by the general formula: [M(II)1−xM(III)x(OH)2][An−·mH2O], where M(II) and M(III) are the divalent (e.g., Mg2+, Zn2+, Ca2+, Co2+, Ni2+, etc.) and trivalent (e.g., Al3+, Fe3+, Cr3+, etc.) metal ions, An− and H2O is the interlamellar anion (e.g., Cl¯, Br¯, NO3¯, CO32¯, SO42¯, SeO42¯) for charge‐neutralization and hydrated state, respectively. They have been widely used in different industry sectors, in materials science and research. Polymer/LDH nanocomposites have gained significant attention in recent years.Carbon‐based nanomaterials, like fullerene, carbon nanotubes (CNT), graphene and graphene oxide have attracted significant attention. Fullerene molecules (C60, C70) are used as reinforcing material for polymers to improve their mechanical, thermal, optical, energy storage and charge transport properties.ObjectivesC60‐doped ZnAl‐layered double hydroxide/polyvinyl alcohol nanocomposites were successfully synthesized and their photocatalytic activity for photodegradation of methylene blue (MB) synthetic dye was quantitatively analyzed by ultraviolet (UV) spectroscopy. The effect of C60 on the optical, structural, morphological properties, and photocatalytic activity of LDHs was investigated, and the impact of C60/LDH mass ratio and aging time on the properties was also studied.MethodsFullerene‐doped ZnAl‐LDH/PVA nanocomposites were synthesized via urea hydrolysis and coprecipitation‐coformation method. First, 10 wt% PVA/water solution (40 mL) is added into the mixed solution containing 0.015 mol of Zn(NO3)2·6H2O and 0.005 mol of Al2(SO4)3·9H2O and titrated by 2 M of NaOH and 1 M of NaHCO3 mixed base solution to adjust pH 9. The obtained white slurry was shaken very hard and aged for 1 year. The obtained samples were marked by the mass percentage of C60 as 1% C60@LDH/PVA, 10% C60@LDH/PVA, 20% C60@LDH/PVA, and 60% C60@LDH/PVA.Results and DiscussionThe basal spacing of C60‐doped ZnAl‐LDH was estimated to be 9.217 Å which is wide enough from the general LDH (~7.0 Å). The crystallite size of nanoparticles is 9.217 nm and ~6 nm by Scherrer's equation and Williamson–Hall method from the XRD data, respectively. Rice‐shaped 2D morphology was formed with 100 nm–2 μm width and 500 nm–10 μm in length by SEM. The maximal photodegradation efficiency was found with 20% of C60 doping (PD% = 96.98) after 360 min, where the sorption efficiency with this compound is very high (R% = 85.55).ConclusionsIn the presented work, the effect of C60 on the optical, structural, morphological properties, and photocatalytic activity of LDHs was investigated, and the impact of C60/LDH mass ratio and aging time on the properties was also studied. For the identification of the photocatalytic activity of obtained C60/LDH nanocomposites, MB was used as a model pollutant and the efficiency of the Zn/Al LDH nanocomposite, with various quantities of fullerene, is also evaluated.

“…This is because activated carbon exhibits competitive adsorption properties and the potential for low cost, high efficiency, simplicity of design, and operation resulting in high adsorption performance, porous structure, easy modification with other materials and large specific surface area. Various literature studies report that carbon-based materials can be made with various agricultural wastes such as durian peel (Ayu et al2020), orange peel (Xie et al 2014), banana peel (Viena et al 2019), rice husk (Palapa et al 2021) , algae, sludge (Nazal n.d.), and rambutan peel (Normah et al 2021).…”

<p>Synthesis of Ni/Al-LDH prepared into Ni/Al-Hc composites using hydrochar from rambutan peel (Hc) and applied as a congo red adsorbent and analyzed based on adsorption selectivity, kinetics, isotherms, adsorption thermodynamics and recycling. The success of Ni/Al-Hc composite preparation was proven by XRD, FT-IR, and BET analysis which showed the unique characteristics of Ni/Al and Hc. The results of the analysis of adsorbent characterization using XRD showed that the peaks in the Ni/Al-Hc composite were similar to typical peaks of Ni/Al appearing around 10.9°(003), 45.5°(018) and hydrochar appearing around 22°(002). The results of the analysis were strengthened by characterization using FT-IR which showed that the Ni/Al-Hc composite had similar spectra with the precursor. BET analysis showed that the Ni/Al-Hc composite had an increase in specific surface area to 11.879 m2/g from 5.845 m2/g after Ni/Al was composited with Hc. The adsorption study showed that the Ni/Al-Hc composite showed selective ability to congo red, and was in equilibrium at 100 minutes with a tendency for adsorption to follow pseudo first order (R2 is closer to 1). The adsorption isotherm shows that the adsorption of Congo red tends to follow Freudlich with the maximum adsorption capacity reaching qm (adsorption capacity) of 246.23 mg/g each using Ni/Al-Hc adsorbent and the adsorption process takes place by physisorption, spontaneous and endothermic. The adsorption regeneration ability is more stable up to the fourth cycle compared to Ni/Al-LDH and Hc with the best desorption reagent using hydrochloric acid.</p>
