This study examines the improved degradation of Indigo Carmine (IC) dye using a ternary nanocomposite made of ZnFe₂O₄, g-C₃N₄, and reduced graphene oxide (rGO), in combination with micro-nanobubble technology. The nanocomposite was synthesized using hydrothermal method, promoting effective interaction between ZnFe₂O₄, g-C₃N₄, and rGO, which enhances photocatalytic performance. The ZnFe₂O₄/g-C₃N₄/rGO nanocomposite (ZGR NCs) exhibited a 92 % degradation efficiency of IC dye within 60 min, significantly outperforming ZnFe₂O₄ (49 %), ZG (59 %), ZR (64 %), and ZGR without MNB (72 %). The photocatalytic process followed pseudo-first-order kinetics with a high correlation coefficient (R² ∼ 0.9789–0.9968), demonstrating the efficiency of charge separation and transfer facilitated by rGO. ZnFe₂O₄ excels in absorbing visible light, g-C₃N₄ serves as a capable photocatalyst with a suitable bandgap for visible light, and rGO further facilitates electron mobility, minimizing charge recombination. Also, the combination of ZnFe₂O₄, rGO, and g-C₃N₄ generates a synergistic effect that significantly boosts photocatalytic activity. This interaction leads to more effective production of reactive oxygen species, which are essential for degrading pollutants. The nanocomposite also exhibited excellent reusability, retaining 88 % of its initial efficiency after five cycles. Additionally, antibacterial studies revealed strong inhibition zones against <em>Streptococcus mutans</em> (18–22 mm) and <em>Enterococcus faecalis</em> (14–20 mm), attributed to ROS-induced bacterial membrane disruption. These findings highlight the multifunctionality of the ZGR nanocomposite-micro-nanobubble (MNBs) system, offering a promising approach for sustainable wastewater treatment and antibacterial applications.</div></div>","PeriodicalId":11716,"journal":{"name":"Environmental Nanotechnology, Monitoring and Management","volume":"23 ","pages":"Article 101065"},"PeriodicalIF":0.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid nanocomposite, GZC (Graphene-ZnO@C-dots), was synthesized through a microwave-assisted method, leveraging the distinct physicochemical properties of each component to significantly enhance sensor performance. Electrochemical analysis conducted via cyclic voltammetry (CV) revealed a marked improvement in electron transfer efficiency and redox behavior compared to unmodified graphene electrodes, attributed to the synergistic interaction among ZnO NR, C-dots, and graphene. The GZC-based electrode demonstrated exceptional sensitivity in detecting fipronil, achieving an impressively low limit of detection (LOD) of 0.00490 µg/L and a limit of quantification (LOQ) of 0.01633 µg/L, outperforming numerous previously reported sensors. A strong linear correlation (R² = 0.9931) was observed between the oxidation peak current and fipronil concentration, indicating excellent analytical performance. Additionally, the sensor exhibited high stability and reproducibility, with a relative standard deviation (RSD) of 0.26 % over 20 consecutive measurements. Validation using a commercial pesticide sample confirmed the sensor’s ability to detect fipronil at trace levels with high accuracy. Moreover, the Horwitz Ratio (HorRat) of 0.024 underscores the superior reproducibility of the sensor, well below the theoretical threshold. The GZC nanocomposite electrode provides a reliable, efficient, and highly sensitive platform for detecting fipronil in environmental samples, showcasing its potential in environmental monitoring to enhance food safety and environmental health through early pesticide residue detection.</div></div>","PeriodicalId":11716,"journal":{"name":"Environmental Nanotechnology, Monitoring and Management","volume":"23 ","pages":"Article 101067"},"PeriodicalIF":0.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
