“…Figure 5d shows that M-GO-γ-MPS was surrounded by a gray and semitransparent liquid, possibly due to the surrounding DES layer. On the other hand, GO nanosheets have also been doped with ZnO and Ni 3 V 2 O 8 for the photocatalytic degradation of cefixime trihydrate (CFX) [62], and anionic (MB, MO) and cationic dyes (crystal violet (CV)) [63], respectively. For instance, the optimal CFX photo-degradation efficiency reached 86% with a catalyst dose of 0.532 g L −1 , an initial CFX concentration of 20.13 mg L −1 , and a pH of 4.03, under UVA irradiation.…”

The use of environmentally friendly deep eutectic solvents (DES) in green synthesis of different types of nanoparticles has garnered increasing interest in recent years. The application of these materials in water treatment, mainly by adsorption or degradation, is emerging as a sustainable alternative to conventional methodologies. However, the information about the green synthesis of nanoparticles (NPs) using DES is dispersed in the literature. This review is focused on compiling and systematizing information regarding DES-mediated NP synthesis, the application of these NPs in water treatment, and future perspectives of these technologies. DES represent an excellent alternative to traditional solvents in NP synthesis due to their low toxicity, low cost, and being environmentally friendly. The possible NP surface functionalization with DES is also attractive as it plays a pivotal role in processes related to water treatment. Modification and synthesis of carbon nanotubes, graphene oxides, magnetic iron oxides, among others, for the adsorption and degradation of organic dyes, pharmaceuticals, metal ions, herbicides, pesticides, and other water contaminants found in recent literature are presented in this work. Finally, the possibility to control NP size and shape can be helpful in the design of new materials for a specific application.

“…These photoinduced e/h pairs can begin subsequent attacks the molecules of the pollutant to degrade them. They also can react with the dissolved oxygen and water molecules to produce the superoxide and hydroxyl radicals, respectively, as powerful oxidizing center to attack the pollutant used (Ciğeroğlu, Şahin, & Kazan, 2022;Esmaili, Solaimany Nazar, & Farhadian, 2017;Nam, Woo, & Han, 2009).…”

A novel coupled Cu2O-CdS-BiVO4-WO3 quadripartite nanoscale catalyst was prepared and characterized by XRD, SEM-DX, x-ray mapping, and DRS techniques. Its pHpzc was also determined to be about 9. The photodegradation experiments were designed via RSM. The optimal run in the photodegradation of sulfasalazine (SSZ) included the CSSZ: 7 mg/L, pH 6.25, 30 min irradiation time, 0.45 g/L of the catalyst dose, by a catalyst with a Cu2O-CdS-BiVO4-WO3 mole ratio 3:1:1:1 under visible light illumination. The effects of the scavenging agents were also studied, and the results confirmed the critical role of superoxide in SFSZ photodegradation and the hydroxyl radicals. The photodegradation pathway obeyed the direct Z-scheme mechanism, which involved three successive binary Z-scheme components involving WO3-BiVO4, BiVO4-CdS, and CdS-Cu2O, which accumulates the photoinduced electrons in the CB-Cu2O and the holes in the VB-WO3, the more powerful reducing and oxidizing centers, respectively.

“…Among these, one of the most commonly used antibiotics is cefixime trihydrate (CFX), which used to treat a variety of bacterial infections, including bronchitis and gonorrhea. Several photocatalysts have been reported for its degradation, such as a ZnO/GO nanocomposite, which yielded 86% CFX degradation [ 17 ]; ZnBi 2 O 4 nanoparticles, which yielded 89% CFX degradation in sunlight within 30 min of irradiation [ 18 ]; a Fe 3 O 4 /TiO 2 nanocomposite core-shell, which degraded CFX within 25 min [ 19 ]; and a g-C 3 N 4 nanocomposite of Fe 3 O 4 /TiO 2 , which reportedly degraded 98 % of CFX [ 20 ]. These examples demonstrated that the degradation efficiency of antibiotics especially depended upon several surface factors of the prepared photocatalysts.…”

The present work was carried out to synthesize bismuth ferrite (BFO) nanoparticles by combustion synthesis, and to evaluate the photocatalytic activity of synthesized bismuth ferrite nanoparticles against cefixime trihydrate. BFO nanoparticles were successfully synthesized using bismuth (III) nitrate and iron (III) nitrate by a combustion synthesis method employing different types of fuels such as maltose, succinic acid, cinnamic acid, and lactose. The effects of the different types of fuels on the morphology and size of the bismuth ferrite nanoparticles were investigated. Characterization of the as-obtained bismuth ferrite nanoparticles was carried out by different techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy-Dispersive Spectroscopy (EDS), N2-sorption analysis, Fourier-transform infrared spectroscopy (FT-IR), and ultraviolet-visible (UV–vis) spectroscopy. Photoluminescence studies were also carried out for the various bismuth ferrite nanoparticles obtained. Degradation of cefixime trihydrate was investigated under sunlight to evaluate the photocatalytic properties of the bismuth ferrite nanoparticles, and it was found that the bismuth ferrite nanoparticles followed first-order degradation kinetics in solar irradiation in the degradation of antibiotic, cefixime trihydrate.
