“…The source of the carbonate anions in the interlayer region of LDHs can be attributed to the dissolution of CO 2 molecules in distilled water used for synthesis [ 15 ]. The peak centered at about 1600 cm −1 is due to the bending vibration of water molecules that exist in the interlayer region of LDHs [ 44 ]. The strong and broad band observed in the wavenumber of 3500 cm −1 can be assigned to the O-H groups attached to the layer surface of the LDHs and the O-H groups of the interlayered water molecules [ 45 ].…”

The application of layered double hydroxide (LDH) nanomaterials as catalysts has attracted great interest due to their unique structural features. It also triggered the need to study their fate and behavior in the aquatic environment. In the present study, Zn-Fe nanolayered double hydroxides (Zn-Fe LDHs) were synthesized using a co-precipitation method and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and nitrogen adsorption-desorption analyses. The toxicity of the home-made Zn-Fe LDHs catalyst was examined by employing a variety of aquatic organisms from different trophic levels, namely the marine photobacterium Vibrio fischeri, the freshwater microalga Pseudokirchneriella subcapitata, the freshwater crustacean Daphnia magna, and the duckweed Spirodela polyrhiza. From the experimental results, it was evident that the acute toxicity of the catalyst depended on the exposure time and type of selected test organism. Zn-Fe LDHs toxicity was also affected by its physical state in suspension, chemical composition, as well as interaction with the bioassay test medium.

“…[47][48][49] Based on the unique properties of GO and LDH materials, recently, the focus on the combined systems of GO and LDHs has received special attention. [50][51][52] Furthermore, the introduction of Fe 3 O 4 to GO is proven as a convenient route because of providing high catalytic activity and easy separation of catalyst from reaction mixture via an external magnet. [53] Strong metal-support interaction also plays an important role in controlling size, stability, and catalytic performance.…”

In the present study, a heterogeneous palladium catalyst system, Pd nanoparticles supported on MRGO@CoAl-LDH, was synthesized and employed in reductive carbonylation of nitroarenes and carbonylative Suzuki coupling reactions using formic acid as CO and H 2 source. The as-obtained heterogeneous catalyst was characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDAX), thermal gravimetric analysis (TGA), and vibrating sample magnetometer (VSM). The nanocatalyst was reused for 5 cycles with a negligible reduction in the yield of products. All reactions were carried out with high yields and under suitable and safe conditions. Also, we have successfully applied formic acid as a good and safe alternative to CO and H 2 gases.

“…Therefore, it is necessary to remove toxic dyes before discharging them into the en-vironment which can be undertaken by oxidation processes (AOPs) based on the oxidation through reaction with hydroxyl radicals (•OH). Photocatalysis has been established as an effective advanced oxidation process [24] and of great interest due to efficiency, environmentally-friendly and high-throughput properties [25].…”

Bismuth oxide synthesis using hydrothermal method has been conducted. This study aims to examine the effect of the hydrothermal reaction time on product characteristics and photocatalytic activity in degrading methyl orange dye. Bismuth oxide synthesis was initiated by dissolving bismuth nitrate pentahydrate (Bi(NO3)3.5H2O) and Na2SO4 in a distilled water and added NaOH gradually. The solution formed was transferred into a Teflon-lined autoclave and heated at 120 °C with time variations of 8–16 h. The formation of bismuth oxide was indicated by the vibrations of the Bi−O−Bi and Bi−O groups and the crystal structure consisting of a-Bi2O3, β-Bi2O3, and g-Bi2O3. In addition, the highest photocatalytic activity can be examined through several factors, such as: content of Bi−O−Bi and Bi−OH groups, crystal structure, band gap values, morphology, and surface area, acquired as a result of the effect of hydrothermal reaction time.
