Composite Hydrothermal method Structural characterization EDX XRD SEMWith the discovery of inorganic semiconductors, silicon and germanium became very important materials in the field of electronics. The use of these materials with these limited features for a long time has become insufficient in the face of increasing demands. For this reason, organic semiconductors have revolutionized structures that respond to these demands. In this study, we synthesized ZnO based semi-material with the hydrothermal method. Structural characterizations were made by XRD, SEM (EDX) and FTIR.

“…This process can help decrease the bandgap and slow down the recombination rate of the electron-hole pairs. Güler et al (2016) (Güler, Güler, Evin, & Islak, 2016) investigated the influence of milling time and Fe2O3 content on the optical and electrical properties of ZnO and the results showed enhanced properties with potential for photocatalysis. Reddy et al (2019) (Reddy et al, 2019) evaluated the photocatalytic activity of Fe doped ZnO nanoparticles obtained by HEBM.…”

This work evaluates how the High Energy Ball Milling (HEBM) in a shaker mill influences the optical, physical, and microstructural properties of ZnO. The procedure also combines Fe inclusion from the grinding medium with particle size reduction. ZnO powder was milled by 1, 2, 3, 4, and 5 h, which resulted in a particle size reduction to the nanometric scale with a mean size of around 50 nm and a crystallite size reduction by three times when processed from 4 h. Milling has proven to be an efficient process for obtaining nanoparticles with an incredibly short processing time and changed the morphology of the particles from random to spherical shapes. Results also indicate the processing progressively expanded the ZnO hexagonal structure due to the imposed strain and Fe inclusion, which can help to decrease the bandgap and slow down the recombination rate of the electron-hole pairs, improving the photocatalysis activity. The optical results showed no additional band appeared due to milling processes and diminished the bandgap from 3.37 to 3.21 eV. Milling also led to an increase in the c value from 5.2076 to 5.2112 Å, which is one of the most important factors for improved antibacterial activity. HEBM has proved to be a suitable process for obtaining ZnO nanoparticles with properties useful for various applications.

Water pollution is a global concern. Inorganic and organic pollutants constitute primary pollutants in water resources. Therefore, it is of great concern to develop advanced sorbent materials for effective and efficient removal of metals and oil from water. In this study, synthesis of new LDH composites which would be used for sorption of heavy metals and oils from polluted water. For this purpose, MgAlOHɣ-Fe2O3-MoS2 composite was prepared and characterizations were performed by FT-IR and XRD. The XRD powder pattern of the composite showed that it contained -Fe2O3, MgAl(OH)14.xH2O and MoS2. Thermal stability of the composite was investigated via DTA/TG technique. MgAlOH-ɣ-Fe2O3-MoS2 composite showed highly efficient sorption for vegetable oil up to 418% times of its own weight. The ability of MgAlOHɣ-Fe2O3-MoS2 composite for removing Pb 2+ ions from aqueous solution. Pb 2+ ion analysis was made by ICP-OES. The effect of Pb 2+ amounts, pH, sorbent amounts, and solvent flow rate on the adsorption capacity of MgAlOHɣ-Fe2O3-MoS2 composite were also investigated.
