Disposing of wastewater contaminated with dyes into the environment results in water pollution, which endangers aquatic life and leads to severe health issues for all living species. Zinc oxide-assisted heterogeneous photocatalysis is a significant approach treating dyes. However, its wide energy gap, activated only by UV light, high electron hole pairs recombination rate constrain photocatalytic activities. This review emphasizes impact doping ZnO transition metals non-metals on dye degradation. Both significantly enhances ZnO's photoactivity reducing band shifting absorption edge visible spectrum, producing more oxygen vacancies crystal defects, decreasing conduction electrons valence holes, boosting surface area. The characteristic nanostructures contingent upon their physiological characteristics, including morphology, particle size. It also includes data from literature regarding some dyes' potential degradation pathways mechanisms using ZnO-based photocatalysts. Molecular other reactive species, O2•−, HO2•, H2O2, •OH, produced series reactions, play part degrading effect several operational parameters photodegradation efficiency has been studied detail, solution's pH, concentration, contact time, photocatalyst dose, oxidizing agents, reaction temperature, light intensity. looks at various techniques utilized prepare Future perspectives challenges photocatalysts are discussed.

Lung cancer is the foremost diagnosed in men and second most common worldwide, highlighting need for new treatment strategies. In current study, AgZnO bimetallic nanoparticles (NPs) with average size of 11 nm were successfully synthesized using Salvia officinalis (SO) extract. The as-synthesized NPs characterized by several microscopic spectroscopic techniques. distribution nanoparticle curve was ranged from 10 to 20 nm, particle diameter approximately 15.6±4.3 zeta potential value -31.1±5.2 mV. Also, EDX technique revealed that weight percentage Zn, O, Ag 5.9 %, 3.6 90.5 respectively. cytotoxicity assessed against A549 lung cells human non-tumorigenic epithelial BEAS-2B cells. showed biocompatibility heathy cells, while they high addition, demonstrated higher compared AgNPs SO extract, indicating synergistic effect between ZnO structure nanoparticle. apoptosis necrosis extract 11.6% (3.69% early 8.07% late apoptosis) 2.79%, On other hand, 29.74% (5.04% 24.7% 9.09%, found through apoptosis, owing upregulation proapoptotic genes (caspase-3, caspase-8, caspase-9, P21, BAX) downregulation antiapoptotic migration (BCL2, cyclin E, D1, MMP-2, MMP-9) treated illustrated lower ability those S. role NP cytotoxicity. arrested during sub-G1 phase increased significantly after (p < 0.05) (17.8% 38% NPs). results this study prove enhanced anticancer due which could be further investigated application.

Globally, the textile industry contributes to pollution through accidental discharges or discharge of contaminated wastewater into waterways, significantly affecting water quality. These pollutants, including dye molecules, are environmental hazards for aquatic and terrestrial life. The field visible light-mediated photocatalysis has experienced rapid growth, driven by utilization photocatalysts that can absorb low-energy light effectively degrade dyes. In present study, we report a simple method controllably synthesize Fe2O3, ZnO, ZnFe2O4 using one-pot synthesis method. subsequent step, copper (Cu) was deposited on surface (forming ZnFe2O4-Cu) facile, green, cost-effective synthesized samples were characterized various techniques, XRD, UV-Vis DRS, FT-IR, SEM-EDX, HR-TEM, XPS, PL, BET analysis. techniques employed investigate composition, morphology, structure, photophysical properties as-prepared samples. ZnFe2O4-Cu nanocomposite demonstrated efficient photocatalytic activity degrading RhB pollutants under light. photocatalyst successfully reused three consecutive cycles without decreasing performance. Furthermore, during radical scavenging test emphasized role different radicals in degradation pollutants. This research potential enable production high-performance rapidly eliminate ecologically harmful dyes from aqueous solutions.
