“…The sol-gel process is a bottom-up, wet-chemical technique widely used in material research related to science and technology applications, in particular for metal oxide nanoparticle synthesis. This process is a combination of two steps, hydrolysis and polycondensation of suitable molecular precursors (usually metal alkoxides or chlorides), which leads to the gradual formation of the solid-phase network [23]. The main benefits of sol-gel chemistry are the high purity and uniformity of nanostructures achievable at low temperatures and the possibility of using different precursors [24].…”

The SiO 2 -Fe 3 O 4 core-shell nanostructures were synthesized by sol-gel chemistry. The morphological features of the nanostructures were examined by field emission scanning electron microscopy which revealed the core-shell nature of the nanoparticles. X-ray diffraction studies evidenced the formation of SiO 2 -Fe 3 O 4 core-shell nanostructures with high degree of homogeneity. The elemental composition of the SiO 2 -Fe 3 O 4 core-shell nanostructures was determined by energy-dispersive X-ray spectroscopy analysis. Fourier transform infrared spectroscopy showed the Si-O-Fe stretching vibrations. On analysis of the optical properties with UV-Vis spectra and Tauc's plot, it was found that the band gap of SiO 2 -Fe 3 O 4 core-shell nanostructures diminished to 1.5 eV. Investigation of the electrical properties of the core-shell nanostructures using field-dependent conductivity measurements presented a significant increase in photoconductivity as compared to those of its single components, thereby rendering them as promising candidates for application as photoelectrodes in dye-sensitized solar cells.

“…In the synthesis of this work, by the sol-gel method, oxalic acid was used to form the medium complex compounds with Zn 2+ and Cu 2+ , where ethylene glycol was used as a dispersing agent. Then, after being dried at 200°C to remove all free water as well as ethylene glycol, the mixture powder that consisted of metallic organic compounds will have a much lower calcination temperature (500°C) to form CuO-ZnO compared to other methods [35,36].…”

In this study, CuO-ZnO composite was synthesized via the sol-gel method using oxalic acid to form the medium complex and its applications in antibacterial have been conducted with B. cereus, E. coli, S. aureus, Salmonella, and P. aeruginosa. Then, nanopowder of CuO-ZnO was coated on shoe insoles and their antibacterial effect with S. aureus was tested. The nanocomposite products were characterized by XRD, XPS, SEM, TEM, and UV-Vis. The results showed that the CuO-ZnO composite has the average particle size in a range of 20-50 nm, the point of zero charge of 7.8, and the bandgap of 1.7 eV. XPS result shows the composite structure with Cu2+ in the product. The minimum inhibitory concentration (MIC) of CuO-ZnO nanocomposite was 0.313 mg·mL-1 for S. aureus and Samonella, 0.625 mg·mL-1 for E. coli, and 5 mg·mL-1 for B. cereus and P. aeruginosa. The shoe insoles coated with 0.35 wt.% of CuO-ZnO nanocomposite also had high antibacterial activity against S. aureus, and this antibacterial nanocomposite was implanted durably on the surface of the shoe insoles.

“…Catalysts have been widely studied for the degradation of dyes, so a wide range of them have been developed, such as metals, metal oxides, semiconductors, metal-organic frameworks (MOF), even quantum dots, dendrimer with magnetic core, among others [20]. Several strategies were developed for their syntheses, such as coprecipitation, flame hydrolysis, microwave radiation, impregnation, sol-gel method, hydrothermal and solvothermal techniques, chemical vapor deposition method, electrodeposition method, and electrospinning, among others [71,72].…”

The use of food additives (such as dyes, which improve the appearance of the products) has become more prominent, due to the rapid population growth and the increase in demand for beverages and processed foods. The dyes are usually found in effluents that are discharged into the environment without previous treatment; this promotes mass contamination and alters the aquatic environment. In recent years, advanced oxidation processes (AOPs) have proven to be effective technologies used for wastewater treatment through the destruction of the total organic content of toxic contaminants, including food dyes. Studies have shown that the introduction of catalysts in AOPs improve treatment efficiency (i.e., complete decomposition without secondary contamination). The present review offers a quick reference for researchers, regarding the treatment of wastewater containing food dyes and the different types of AOPs, with different catalyst and nanocatalyst materials obtained from traditional and green chemical syntheses.
