Environmental consequences during the COVID-19 pandemic have attracted attention due to the excessive use of antibiotics which lead to the release of the drug's residue, such as amoxicillin (AMX), into the environment. In this work, an advanced oxidation process based on a visible, active N-doped TiO2 photocatalyst was carried out to eliminate AMX. Nitrogen with different initial doping concentrations (15, 30, 45% w/w) was doped into TiO2 by the sol-gel method. The characterization technique such as XRD, FTIR, UV-SRS, and SEM-EDX revealed that nitrogen with 30% doping concentration improved the TiO2 response in the visible region, attributed to the lower band gap energy (2.97 eV). In the photodegradation processes, the TiO2-N (30%) photocatalyst possessed higher AMX degradation than undoped TiO2 for both UV and visible light irradiation. In an aqueous solution, the degradation percentage of AMX by TiO2-N (30%) was 68.5 and 84.12%, while the degradation percentage of AMX by TiO2 was 38.7 and 78.01% under visible and UV light, respectively.

“…However, amoxicillin in water or in the ecological environment is considered an emerging pollutant because it can cause several health effects to aquatic life in the presence of solved molecules in water [ 16 ]. There are some reports regarding the use of different photocatalytic materials to degrade amoxicillin [ 96 ]. For instance, the photocatalytic degradation of amoxicillin by as-prepared titanium dioxide nanoparticles loaded on graphene oxide (GO/TiO 2 ) by the chemical hydrothermal method was evaluated under UV light by Balarak et al, and the experimental data exhibited that key indexes such as initial pH, GO/TiO 2 dosage, UV intensity, and initial amoxicillin concentration all had a significant impact on amoxicillin degradation ( Figure 10 a) [ 97 ].…”

The existence of antibiotics in the environment can trigger a number of issues by fostering the widespread development of antimicrobial resistance. Currently, the most popular techniques for removing antibiotic pollutants from water include physical adsorption, flocculation, and chemical oxidation, however, these processes usually leave a significant quantity of chemical reagents and polymer electrolytes in the water, which can lead to difficulty post-treating unmanageable deposits. Furthermore, though cost-effectiveness, efficiency, reaction conditions, and nontoxicity during the degradation of antibiotics are hurdles to overcome, a variety of photocatalysts can be used to degrade pollutant residuals, allowing for a number of potential solutions to these issues. Thus, the urgent need for effective and rapid processes for photocatalytic degradation leads to an increased interest in finding more sustainable catalysts for antibiotic degradation. In this review, we provide an overview of the removal of pharmaceutical antibiotics through photocatalysis, and detail recent progress using different nanostructure-based photocatalysts. We also review the possible sources of antibiotic pollutants released through the ecological chain and the consequences and damages caused by antibiotics in wastewater on the environment and human health. The fundamental dynamic processes of nanomaterials and the degradation mechanisms of antibiotics are then discussed, and recent studies regarding different photocatalytic materials for the degradation of some typical and commonly used antibiotics are comprehensively summarized. Finally, major challenges and future opportunities for the photocatalytic degradation of commonly used antibiotics are highlighted.

This research focuses on the preparation and characterization of TiO2 thin films in both pure and doped forms. The films were deposited onto glass substrates using the spray pyrolysis technique. The pure film was doped with Cu, Co, and Zn at a constant ratio of 3 wt% in the starting solution. XRD analysis revealed the presence of anatase TiO2 phase in all deposited films. The crystallite size of the pure film was determined using Scherer’s equation and found to be 8.3 nm, while the doped films had sizes of 11.3 nm (Cu), 13.8 nm (Co), and 11.3 nm (Zn). SEM images showed the formation of fine grains with a normal distribution, with average sizes of 27.02 nm (pure), 39.37 nm (Cu), 33.4 nm (Co), and 29.37 nm (Zn) for the respective doped TiO2 films. EDX analysis confirmed the presence of the dopant elements in the deposited films. It was observed that all films exhibited a direct band gap, with a value of 3.79 eV for the pure film, which slightly decreased upon doping. Additionally, various optical constants such as refractive index, extinction coefficient, dielectric constant, relaxation time, and optical mobility were estimated and presented in this study.
