The nanoparticles were synthesized using a deep eutectic solvent (DES)-assisted solvothermal method, a technique known for its precision and reproducibility. It resulted in materials with high thermal stability, excellent catalytic activity, and enhanced electronic properties. The synthesized CeW, SmW, and GdW were employed to modify screen-printed carbon electrodes (SPCEs), a widely used and well-established method in the field, which were then characterized using various techniques. Electrochemical performance was evaluated through cyclic voltammetry, differential pulse voltammetry, and amperometric (<i>i-t</i>) responses, all of which are standard methods in electrochemical analysis. The modified electrodes exhibited superior electrochemical behavior compared to bare SPCEs, with CeW/SPCE showing the highest reduction peak current for 4-nitrotoluene detection. The linear range for detection was found to be for DPV= 0.01–576 μM and for <i>i-t</i> = 0.001–306 μM, with a limit of detection of DPV = 0.034 μM and <i>i-t</i> = 0.012 μM. The sensors demonstrated excellent selectivity, reproducibility, and stability, with minimal interference from other substances commonly found in environmental samples. Real-world applicability was confirmed by testing the modified electrodes in the river and tap water samples spiked with 4-nitrotoluene. The CeW/SPCE sensor showed rapid and sensitive response in both matrices, highlighting its potential for environmental monitoring. The robust performance of CeW, SmW, and GdW-modified electrodes underscores their suitability for practical applications in detecting nitrophenols, contributing to effective environmental monitoring and pollution control. This research has the potential to inspire further advancements in the field of electrochemical detection and environmental monitoring.</p>","PeriodicalId":29804,"journal":{"name":"ACS Engineering Au","volume":"4 6","pages":"533–544 533–544"},"PeriodicalIF":4.3,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsengineeringau.4c00024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional photocatalytic methods for eliminating harmful dyes are often ineffective and are environmentally damaging. This study introduces a new, efficient photocatalyst combining Dy₂O₃ with TiO₂ using a single-step hydrothermal approach. Dy₂O₃@TiO₂ nanostructures were synthesized and characterized by using XRD, SEM, EDS, TEM, BET, and UV–visible spectroscopy. Dy₂O₃ was evenly distributed on TiO₂, preventing clumping and resulting in a larger surface area with more active sites. UV irradiation (365 nm) replaced the traditional thermal energy for photocatalytic dye breakdown, leveraging the varying conductivity of the Dy₂O₃@TiO₂ nanocomposites. Incorporating Dy₂O₃ decreased band gaps, enhancing redox reactions and expanding the range of degradable contaminants. For Rhodamine B dye degradation, the Dy₂O₃@TiO₂ composite demonstrated significantly higher degradation rates than Dy₂O₃ or TiO₂ alone at reaction parameters such as neutral pH (pH 7) and catalyst concentration (2 g L^–1). The hybrid material also demonstrated improved electrocatalytic activity in oxygen reduction reactions (ORRs) under alkaline conditions with an initial potential of 0.88 V and a Tafel slope of 73 mV dec^–1. The enhanced catalytic activity and durability are attributed to the synergistic interaction between Dy₂O₃ and TiO₂. This novel photocatalyst offers a sustainable alternative for treating industrial effluents while reducing the environmental impact.","PeriodicalId":29804,"journal":{"name":"ACS Engineering Au","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142264629","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}
