“…Moreover, the peak at 582 cm −1 in the FTIR spectrum of Fe‐CS sample (Figure 6a), as well as the two intense peaks at 582 and 610 cm −1 bands of the Fe 3 O 4 ‐CS sample were due to the stretching vibration mode associated to the Fe‐O absorption band 21 . Likewise, the two peaks at 617 and 596 cm −1 in the Mn‐CS and MnO 2 ‐CS spectra in Figure 6b could be attributed to the Mn‐O vibration 22 . The band around 540 cm −1 in the TiO 2 ‐CS sample was due to the titanium oxide and assigned to the stretching vibration of Ti‐O 23 …”

Photocatalytic degradation of Amitraz insecticide in a heterogeneous phase was studied at neutral pH using several types of metals supported on chitosan beads (Fe‐CS, Fe3O4‐CS, Mn‐CS, MnO2‐CS, and TiO2‐CS). Scanning Electron Microscopy (SEM), X‐Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), and Brunauer Emmett Teller (BET) analysis were used to characterize the prepared catalysts. Parameters, including the type of catalyst, UV irradiation, the method of hydrogen peroxide addition, and the presence of dissolved oxygen were investigated in order to evaluate the performance of the heterogeneous Fenton process. The optimal conditions were achieved when using 1 g L−1 of Fe3O4‐CS catalyst under UV irradiation with the sequential addition of 12 mM of H2O2 and a continuous bubbling of air in the reactional medium. The degradation of the pollutant follows a pseudo‐first‐order kinetic. The catalyst stability was evaluated and confirmed in four repeated runs with a control of the amount of leached iron in the aqueous solution.

“…Mixing polymers is a key step in creating novel polymeric materials that can be applied in various situations. One of the primary advantages of utilizing a polymer blend is the ability to customize the characteristics of the end product to fulfill the demands of specific applications, a Feature that cannot be accomplished when utilizing a solitary polymer type [1,2]. Creating a nanocomposite involves combining discrete nanoscale constituents to regulate and improve the structure and properties of the material [3] Increased tensile strength, conductivity, and thermal stability, in addition to reduced flammability [4].…”

This study aimed to investigate the alterations in the structural and optical properties of Poly-methyl-methacrylate (PMMA) and Polystyrene (PS) through the utilization of different weight percentages of Aluminum oxide (Al2O3) nanoparticles (2%, 4%, 6%, and 8%) by weight. The optical microscope images indicate that the distribution of nanoparticles in the blend was uniform, resulting in a continuous network within the polymer matrix. The field emission scanning electron microscope revealed that there was a connection between the interface that connects the polymer matrix and the additive. The optical properties before and after the exposure to Ar plasma exhibited that the absorbance, absorption coefficient, refractive index, extinction coefficient, dielectric constant (real, imaginary) and optical conductivity of (PMMA/PS/Al2O3) nanocomposites increased with the increasing of the concentrations of the Al2O3. The transmittance and the energy gap for indirect transition (allowed, forbidden) decreased with the increasing concentrations of Al2O3 nanoparticles. The optical properties after irradiation are seen to have high values compared with those before the irradiation which is attributed to the increased charge carriers and the occurrence of some bonds breaking. Finally, the results indicated that the (PMMA/PS/ Al2O3) nanostructures can be considered as promising materials for optoelectronics nanodevices.

A novel composite material PIL@TiO 2 was synthesized by sol-gel method using zwitterionic ionic liquid (1-(3-sulfonic group) propyl-3-ethylimidazole). TiO 2 was uniformly loaded on PIL (poly(1-(3-sulfonic group) propyl-3-ethylimidazole)). The large specific surface area, unique microspore structure, negative effect, and synergistic effect were caused by PIL. PIL@TiO 2 can effectively improve the separation efficiency of the electron-hole photogeneration. The electron-hole pair and Á OH play an important role in the photo-degradation. The structure of dye molecule is also an influencing factor for the degradation capacity. After five cycle experiments, PIL@TiO 2 still exhibited excellent photocatalytic efficiency to dye molecules and its photocatalytic efficiency is better than that of P-25 (nanoscale TiO 2 ) in the methyl orange and Rhodamine B solutions.
