Metal oxide nanoparticles (NPs), particularly ZnO NPs, have garnered significant attention in addressing global water-related challenges. This study introduces NPs agents for acidic water treatment by synthesizing nanostructures via ultrasound-assisted green synthesis utilizing Ginger extract. The research investigates the influence of solution pH on physical properties and their photocatalytic efficiencies treating (pH = 5) neutral 7) through photodegradation methylene blue (MB) under ultraviolet (UV) illumination. Results indicate that pH, varying between 7 13, significantly controls morphologies yielding hexagonal plates, barley-like structures, nanoflakes. band gap energies synthesized are quite independent but crystallite sizes decrease with increasing values. Notably, at 11 exhibit highest BET-specific surface area 26.74 m²/g, correlating superior activity. optimal degradation MB conditions reach 93.54% 86.04% when 10 5 mg irradiated photocatalyst, respectively, after a reaction time 160 min. These findings underscore potential as cost-effective environmentally sustainable efficient wastewater treatment.

Nanomaterials including zinc oxide (ZnO) and non-stoichiometric (W18O49) tungsten can be applied to solve the challenge related optical properties of nanomaterials like global problems water treatment. Therefore, successful syntheses oxide-tungsten nanocomposites ZnWO4 nanostructures are reported by hydrothermal method using different masses green synthesized ZnO nanoparticles (NPs). The pure only zinc, tungsten, oxygen elements observed in samples. Alterations NPs mass used nanocomposite synthesis process influence nanocomposites' structural, morphological, properties. Different morphologies nanorods, nanofibers, cabbage-like structures, short nanoflakes formed NPs. photocatalytic activities evaluated removing methylene blue (MB- 10 ppm) under UV irradiation neutral (pH = 7) acidic 5) solutions. Interestingly, mg ZW0.05 demonstrates excellent deterioration MB with efficiencies 99% 91% within 170 min solutions, respectively. Furthermore, quantity catalyst was reduced 5 mg, demonstrating capacity degrade 87% (94%) at pH 7 5). one an candidate for treatment even condition.
