Zn-Layered Double Hydroxide Intercalated with Graphene Oxide for Methylene Blue Photodegradation and Acid Red Adsorption Studies

Catalysts, Год журнала: 2024, Номер 14(12), С. 897 - 897

Опубликована: Дек. 6, 2024

This study focuses on the synthesis of a novel layered double hydroxide and its application in two environmental remediation processes. Graphene oxide, two-dimensional material, has potential applications this field. However, tendency to agglomerate restricts usability. Our objective was increase morphology performance (LDH) by combining GO with hydrotalcite. The LDH/GO nanohybrids were utilized as photocatalysts for degradation methylene blue (MB) dye investigated sorbents acid red (A.R) water. In order achieve objective, ZnAl-NO3 LDH synthesized using co-precipitation method, Zn:Al ratio ~3. Subsequently, intercalated varying ratios as-received graphene oxide. An array analytical techniques, including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), photoelectron (XPS) measurements, N2 physisorption, scanning electron microscopy–energy-dispersive analysis (SEM-EDX), diffuse reflectance UV–vis spectra (DR UV-vis), employed examine physicochemical properties LDH. These techniques confirmed that obtained material is zinc-aluminum hydrotalcite GO. addition oxide (GO) structure improved As result, composite ZnAl-LDH-10 shows significant field photocatalytic MB. Additionally, incorporation enhanced absorption light visible region spectra, leading elimination A.R compared without or other

Abstract Layered Double Hydroxides (LDH) are the 2D nanomaterials having general formula [M 1‐x 2+ M x 3+ (OH) 2 ] x+ [A x/n n− .mH O. They become one of most promising catalysts for various applications because their many unique properties, which include high surface area, uniform atomic level distribution, and acid‐base bifunctionality. In this work metal acetylacetonate was used as a precursor to synthesize Ni‐Al its SiO ‐supported product by nonaqueous sol‐gel method. PXRD, FT‐IR, TGA, BET area pore volume analysis, Zeta potential, particle size SEM, TEM, EDS analysis were characterize them. The mixed‐metal oxides obtained calcinations synthesized LDHs at 450 °C. resulting mixed oxide subsequently employed catalyst N O decomposition process. When : LDH ratio varied, these showed improved °C with changes ratio. presence ratios (2:1) (1:2), around 99.5% conversion noted.

This work focuses on the preparation and application of silver nanoparticles/organophilic clay/polyethylene glycol for catalytic reduction contaminants methylene blue (MB) 4-nitrophenol (4-NP) in a simple binary system. Algerian clay was subjected to series treatments including acid treatment, ion exchange with surfactant hexadecyltrimethylammonium bromide (HTABr), immobilization polyethylene polymer, finally dispersion AgNPs. The molecular weight varied (100, 200, 4000) study its effect stabilization nanoparticles (AgNPs) activity resulting samples. results showed that catalyst highest had AgNP content. Catalyst mass, NaBH4 concentration, type were shown have significant influence conversion rate constant. material nanoparticle content identified as optimal both pollutants. measured constants 164 × 10−4 s−1 25 s−1, respectively. MB 4-NP system high selectivity dye, 64 9 4-NP, reuse best via dye four cycles good without loss performance.
