“…IONPs are also widely utilized in biomedical applications such as drug delivery systems, where the particles can be carried to a specific site with high accuracy due to the use of an external magnetic field to direct the particles [103,104]. Iron oxide NPs are usefully applied in many fields including sensing [105][106][107], catalysis [108][109][110], photodegradation [111,112], and adsorption of pollutants [113][114][115]. The only disadvantage in IONPs is the aggregation of particles in aqueous media, which is unfavorable in water remediation applications.…”

For applications involving water cleanup, metal oxide nanoparticles are exceptionally successful. They are useful for the adsorption and photocatalytic destruction of organic pollutants due to their distinctive qualities, which include their wide surface/volume area, high number of active sites, porous structure, stability, recovery, and low toxicity. Metal oxide nanomaterials have drawn a lot of attention from researchers in the past ten years because of their various production pathways, simplicity in surface modification, abundance, and inexpensive cost. A wide range of metal oxides, such as iron oxides, MgO, TiO2, ZnO, WO3, CuO, Cu2O, metal oxides composites, and graphene–metal oxides composites, with variable structural, crystalline, and morphological features, are reviewed, emphasizing the recent development, challenges, and opportunities for adsorptive removal and photocatalytic degradation of organic pollutants such as dyes, pesticides, phenolic compounds, and so on. In-depth study of the photocatalytic mechanism of metal oxides, their composites, and photocatalytically important characteristics is also covered in this paper. Metal oxides are particularly effective photocatalysts for the degradation of organic pollutants due to their high photodegradation efficiency, economically sound methods for producing photo-catalytic materials, and precise band-gap engineering. Due to their detrimental effects on human health, pesticides—one of the highly hazardous organic pollutants—play a significant part in environmental contamination. Depending on where they come from and who they are targeting, they are categorized in various ways. Researchers focusing on metal oxides and their composites for the adsorptive and photocatalytic degradation of pesticides would find the review to be a beneficial resource. Detailed information on many pesticides, difficulties associated with pesticides, environmental concentration, and the necessity of degradation has been presented.

“…The absorbance was calculated using Equation 4 based on the Kubelka-Munk function [29], in which the light absorption decreased due to the inverse relationship with the reflectance. Additionally, the indirect bandgap values were estimated following the Wood and Tauc method described in Equation 5 [30].…”

Objective: In this paper, the photocatalytic degradation of acetaminophen was evaluated using silver-doped titanium dioxide nanoparticles in a cylindrical-parabolic composed photoreactor. Materials and methods: Titanium dioxide was synthesized via green synthesis using Cymbopogon citratus leaf extract and doped by silver photodeposition. Results and discussion: Morphological information shows that large agglomerates of approximately 49 nm can be attributed to the strong interaction between nanoparticles and their polycrystalline nature. The photodeposition of metallic silver reduces the surface effects, allowing a decrease in the electrostatic interaction and diameter size of the titanium dioxide, as well as the optical properties due to surface poising during the reduction of silver ions to metallic silver. The photocatalytic activity was performed to degrade acetaminophen as the drug model under visible-light radiation. The results are promising, with superior photodegradation of acetaminophen of approximately 37% and 11% for unmodified titanium dioxide and silver-doped titanium dioxide (0.75 at%) nanostructures compared to the commercial photocatalyst, respectively. Conclusions: Accordingly, the potential photocatalytic application of silver-doped titanium dioxide nanostructures is highlighted and represents a promising alternative for the photodegradation of organic compounds from wastewater eluents.
