“…They summarized that the green synthesis approach for both ZnO and TiO 2 nanoparticles is effective in degrading RhB under UV light irradiation, with TiO 2 nanoparticles showing higher photocatalytic activity than ZnO nanoparticles. Another study by Bircan Haspulat Taymaz et al, published in the International Journal of Phytoremediation in 2022 also investigated the synthesis of ZnO nanoparticles using a green Thymus vulgaris leaf extract and their potential photocatalytic properties [11]. The results showed that the synthesized ZnO nanoparticles exhibited good photocatalytic activity in the degradation of methylene blue under UV light irradiation.…”

Rhodamine B (RhB)'s photocatalytic activity was enhanced through the green chemical synthesis of metal oxide nanoparticles (ZnO and TiO2). To produce nanoparticles, zinc nitrate hexahydrate and titanium tetra-isopropoxide precursors were hydrothermally generated using extracts from Vachellia hebeclada. These synthesised nanoparticles were then calcined at high temperatures. Variations in several parameters, including their effects on the crystal size and morphological properties of nanoparticles, were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transforms infrared spectroscopy analysis (FTIR), and UV-vis spectroscopy. With ZnO and 26.9% with TiO2 nanoparticles, the photocatalytic efficiency of RhB degradation under ultraviolet light illumination was 56.9% within 180 minutes. The reaction rate of the ZnO pseudo-first-order kinetics was the highest (0.017 min− 1) while the reaction rate of the TiO2 nanoparticles was the slowest (0.005 min− 1). The driving force for the separation of photo-excited charge carriers is taken away by the reduced photocatalytic activity of mixed-phase TiO2 particles. ZnO nanoparticles with photocatalytic applications can be produced in an environmentally friendly manner through green nano-production. According to these findings, V. hebeclada extract-mediated synthesis of ZnO and TiO2 nanoparticles may have potential applications in the photocatalytic degradation of organic pollutants like RhB. However, additional research is required to improve the synthesis procedure and investigate the effectiveness of these nanoparticles in actual wastewater treatment applications.

“…The water-soluble organic compound methylene blue (MB), as the commonly contaminants in the industrial wastewater with a complex chemical structure and stable properties, is difficult to remove by traditional water treatment technology. − At present, the main technology for removing MB dyes is the physical adsorption method, which mainly uses the abundant pores of adsorbent material to adsorb dyes. − Adsorption is a technology with a high removal rate, low cost, and good prospects. In addition, the extraction method can also separate the dyes from the wastewater by the different solubility of dyes between extractant and water but the extractant used will also cause pollution to the environment. , The ozone method, the electrochemical method, photocatalytic degradation, and other methods can adsorb or degrade dye molecules, so as to achieve the purpose of dye treatment. − …”

Methylene blue (MB) is a water-soluble organic compound with a complex chemical structure and stable properties, which is difficult to remove. In this work, a high specific surface area MB dye adsorbent of 3D hierarchical porous derived carbon was obtained from moldy rice noodles (RN) through high-temperature carbonization and strong alkali etching. The morphology and structural properties, pore structure, specific surface area, and crystallinity of RN carbon (RNC) are analyzed. The adsorption properties of RNC for MB dye molecules are studied, including the influence of different activator (KOH) ratios, the influence of initial concentration of dye, and the influence of adsorption kinetics and thermodynamics on the adsorption of dye. The results show that the optimal ratio of RN to activator is 1:2 (RNC-2), and its specific surface area is the highest, reaching 1693.31 m 2 /g. At 298 K, the maximum theoretical adsorption capacity of RNC-2 is 626.25 mg/g, and at 333 K, the maximum theoretical adsorption capacity is 827.34 mg/g. This work shows that the derived carbon material obtained from moldy RN is a kind of adsorbent material with excellent properties and has a great application prospect in purifying industrial wastewater. This work also means that moldy RN can be recycled rather than discarded. In addition, this material can also be used in fields such as energy storage and catalysis in the future.

CuO-, ZrO 2 -, and ZnO-immobilized functional boron nitride (fBN) nanoparticles were synthesized by an environmentally friendly approach using a Stevia rebaudiana extract. Metal-oxide-immobilized fBN nanoparticles (fBN/MO)-incorporated (1 wt %) polyvinyl alcohol/poly(acrylic acid) composite nanofibers were fabricated by electrospinning, and their antibacterial, antioxidant, and photocatalytic properties were investigated. fBN/CuO and fBN/ ZnO nanoparticles were distributed randomly, showcasing nonuniform geometries besides polygonal-shaped fBN/ZrO 2 nanoparticles. fBN/MO nanoparticles exhibited a uniform dispersion along the composite nanofibers, with diameters between 115 and 160 nm. The incorporation of fBN/MO nanoparticles into the composite nanofibers (0.074−0.753 W/mK) resulted in an improvement in both thermal stability and conductivity when compared with PVA/PAA nanofibers (0.063 W/mK). fBN/MO-modified composite nanofibers exhibited an antibacterial efficacy exceeding 99% against Streptococcus mutans, Acinetobacter baumannii, Escherichia coli, and Staphylococcus aureus, augmenting their antioxidant properties. The modified composite nanofibers, particularly those incorporating fBN/ZrO 2 nanoparticles, exhibited effective photocatalytic remediation against methylene blue (MB) with the highest activity, attributed to their favorable morphological and optoelectronic properties, resulting in a remarkably more than 20-fold improvement. Enhanced stability for repeated treatment of MB for a minimum of three cycles was achieved. The multifunctional nature of nanofibers unveils synergistic antibacterial, antioxidant, and photodegradation effects, positioning them as promising for biomaterials and water disinfection.
