“…The N 2 adsorption-desorption isotherms are shown in Figure 4. Based on the IUPAC classification, all the materials show type IV hysteresis loop isotherms indicating the materials are classified as mesoporous (Ahmad et al, 2024;Mallakpour et al, 2023). The data also shows the physical characteristics of each material, This shows that in this study, the addition of Ch, Ce, and GO materials to Ni/Al-LDH to form a composite will increase the surface area of the material and it proves that the material synthesis was successfully carried out.…”

In this study, the synthesis of composite materials produced from Ni/Al with three types of carbon-based materials namely chitosan (Ch), cellulose (Ce), and graphene oxide (GO) was successfully carried out supported by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), and Brunauer-Emmett-Teller (BET) analysis. The combined characteristics of the two starting materials are present in the composite material based on XRD and FT-IR data. The surface area of Ni/Al-LDH increased after compositing with Ch, Ce, and GO, from 3.3 m2/g to 9.5 m2/g in Ni/Al-Ch, 5.1 m2/g in Ni/Al-Ce, and 78.4 m2/g in Ni/Al-GO. These findings indicate that the materials are suitable for various applications such as photocatalytic and adsorption as effective materials in further research.

“…The higher specific surface area (1282 m 2 g −1 ) improved the adsorption for orange II, and the maximum adsorption amount reached 1173 mg/g. Mallakpour et al [ 69 ] prepared the nanocomposite beads containing chitosan (Chi), tannic acid (TA), LDH, and mixed metal oxides (MMO). The beads were applied for the simultaneous removal of three reactive dyes, and the maximum adsorption capacities of Chi/TA@LDH and Chi/TA@MMO beads were between 257 and 483 mg g −1 .…”

“…However, the filtration process often results in the blockage of membrane pores by oil droplets [ 76 ]. Then, the development of superhydrophilic/superoleophobic films with anti-fouling properties has received much attention [ 68 , 69 ]. Cui et al [ 77 ] prepared the grass-like composite membranes (NiCo-LDH/PVDF) by growing NiCo-LDH on the surface of polydopamine-modified polyvinylidene fluoride (PVDF) membrane using the hydrothermal method.…”

Layered double hydroxides (LDHs) can be used as catalysts and adsorbents due to their high stability, safety, and reusability. The preparation of modified LDHs mainly includes coprecipitation, hydrothermal, ion exchange, calcination recovery, and sol–gel methods. LDH-based materials have high anion exchange capacity, good thermal stability, and a large specific surface area, which can effectively adsorb and remove heavy metal ions, inorganic anions, organic pollutants, and oil pollutants from wastewater. Additionally, they are heterogeneous catalysts and have excellent catalytic effect in the Fenton system, persulfate-based advanced oxidation processes, and electrocatalytic system. This review ends with a discussion of the challenges and future trends of the application of LDHs in wastewater treatment.

“…Therefore, it is necessary to improve the structure by compositing carbon-based materials. Many studies have conducted composites with carbon-based materials such as biochar (Luo et al, 2023) , graphite (Hu et al, 2019) , chitosan (Mallakpour et al, 2023) , and hydrochar (Luo et al, 2020) . According to Zubair et al (2022) , the addition of supporting materials such as carbon-based materials into the matrix in composites will be able to improve the properties of the material and can improve adsorption performance.…”

The successful synthesis and preparation of Zn/Al layered double hydroxide, cellulose, and Zn/Al-cellulose materials were analyzed using XRD, FT-IR, and BET. The diffraction peaks of Zn/Al layered double hydroxide are at 10.3°; 20.3°; 34.8°; and 60.40°, while the diffraction peaks of cellulose are at 15.5°; 22.4°; and 34.5°. Diffraction peaks on Zn/Al layered double hydroxide and cellulose were observed at 3442 cm-1, 1642 cm-1, 1440-1620 cm-1, 1351 cm-1, 1153 cm-1, and 400-800 cm-1. The surface area of the material after the composite increased from 1.968 to 13.615 m2/g. The optimum pH for Zn/Al LDH was pH 4, pH 10 for cellulose, and pH 2 for Zn/Al-cellulose. The isotherm data of Zn/Al LDH and cellulose followed the Freundlich model, while Zn/Al-cellulose followed the Langmuir model. The reuse of adsorbents in the adsorption process can be used up to 3 times.
