“…For further investigation of crystalline nature Zn 2 Al‐CO 3 LDH, selected area electron diffraction pattern (SAED), shown in Figure S2of the individual nanoplates of Zn 2 Al‐CO 3 LDH material were studied and the result exhibits hexagonal patterns showing [110] and [111] planes where the crystals are oriented perpendicular to the basal planes of the LDH. The sharp spots of 110 planes provide the cell parameters a=b=3.06 Å.…”

“…The analysis of FESEM micrographs reveals that crystalline Zn 2 Al‐CO 3 LDH has a mean lateral size of ∼ 250 nm and a thickness of ∼35 nm. Overall, the synthesized sample is of high quality in terms of size, uniformity, morphology, and crystallinity, and those are much superior to the Zn 2 Al‐CO 3 LDH samples reported earlier . The TEM images (Figure c and d) present a thin hexagonal plate‐like crystallite with similar lateral dimensions as those observed by FESEM.…”

“…Also, Non‐transition‐metal M 3+ , especially Al 3+ (Aluminium) based LDH, in general, are reported to be less toxic than other inorganic nanoparticles . Various efforts have been made to channelize Zn 2 Al‐CO 3 LDH towards multiple applications like efficient pollutant removal, excellent sorption abilities, strong toxicity against Staphylococcus aureus and Pseudomonas aeruginosa microorganisms, commendable antibacterial properties, and photocatalytic degradation in water remediation, etc.…”

Due to the accelerating growth of civilian and industrial regime, chemical and bioremediation of water body become a major concern for society. Here, we report a facile and scalable process to get Zinc-aluminium layered double hydroxide (LDH) with carbonate interlayer anion and present it as promising multifunctional material for potential applications in adsorption, antibacterial, and cytotoxicity performances. In this study, the sample was prepared by co-precipitation method and the well crystalline LDH was characterized by Scanning Electron Microscopy (SEM), Transmission Electron Microscope (TEM), X-Ray Diffraction (XRD), X-Ray Photoelectron Spectroscopy (XPS) and Brunauer-Emmett-Teller (BET) analysis. The study shows excellent adsorption capacity of Zn 2 Al-CO 3 LDH as high as 81.4 mg/g against the methyl orange (MO) dye taken as a model organic pollutant. Adsorption kinetics and adsorption isotherms have also been investigated in detail. Moreover, the prepared Zn 2 Al-CO 3 LDH sample shows commendable antimicrobial efficacy against both Gram-negative and Gram-positive bacteria. In addition to that, under cytotoxicity study, the sample exhibits a creditable inhibitory effect towards the cancerous cell HEPG2 cell. As a whole the results show the significant implication of the Zn 2 Al-CO 3 LDHas a multifunctional material towards environmental concern and also as an antimicrobial material.

“…When the intensities of the (110) and (113) peaks are considered, the most intense peaks correspond to the samples synthesized using the conventional method at metallic molar ratios of 3 and 4, denoted as the CN3 and CN4 samples. This indicates that the conventional method promotes a more regular accommodation of the cations in the hydrotalcite lamellae compared to the microwave or ultrasound methods (Lobo-Sánchez et al , 2018). However, a noise increase in the CN samples indicates a reduction in crystal order from CN2 to CN4, and a less visible effect is observed for the MN and UN series.…”

Hydrotalcites with heterogeneous distributions of anions between their layers were synthesized. Some synthesis parameters were studied to verify their influence on the anionic segregation properties of the hydrotalcites. The nature of the divalent cation and the crystallization method were most relevant. Zinc, in contrast to magnesium, assisted in discriminating carbonates and attracting nitrates to form hydrotalcites with heterogeneous distributions using microwave irradiation. Furthermore, the identification of this kind of hydrotalcite could be easily verified by determining the presence of a double reflection in the 003 X-ray diffraction (XRD) maximum, which definitively characterized a heterogeneous anion distribution. Finally, the reason as to why in some cases the hydrotalcite presented two reflections in the 003 XRD peak was elucidated.

Layered double hydroxide (LDH) of Zn/Al and citrate-Zn/Al was prepared and used as an adsorbent of Congo red from aqueous solution. LDH was characterized by X-ray, FTIR, and BET analysis. Adsorption of Congo red was studied through kinetic, isotherm, and thermodynamic analyses. Zn/Al LDH has diffraction at 10.29o (003) with interlayer distance 8.59 Å and citrate-Zn/Al LDHs have anomalous diffraction at 7.57o (003) with interlayer distance 11.68 Å. The surface area of citrate-Zn/Al (40.50 m2 g-1) has higher than pristine LDH (1.97 m2 g-1). Adsorption of Congo red was conducted at pH 6 for Zn/Al LDH and at pH 8 for citrate-Zn/Al LDH. Adsorption of Congo red on both LDHs follows the pseudo-second-order kinetic model. The isotherm parameter follows the Freundlich isotherm model with maximum adsorption capacity 166.67 mg g-1 for Zn/Al and 249.99 mg g-1 for citrate-Zn/Al LDH. Adsorption of Congo red on both LDHs was classified as physical adsorption with energy 4.085-4.148 kJ mol-1.
