The performance of gas sensors is governed by the transport efficiency of charge carriers within the sensing material. Therefore, we propose a new strategy to enhance the electron transport in the selective detection of trimethylamine (TMA) at room temperature by a 2D–2D interface. It is demonstrated in an in–situ growth of SnS₂ nanosheets on a two–dimensional Ti₃C₂T_x surface by a facile one–step hydrothermal method with varying the amount of Ti₃C₂T_x. Electronic structure results proves that Ti₃C₂T_x and SnS₂ are well chemically bonded to each other via Ti–S covalent bonds in the 2D–2D interface. The detection of TMA facilitated by this interface has achieved a low theoretical detection limit (LOD for TMA = 73.58 ppb), excellent selectivity toward TMA, high reproducibility, and long–term stability (12.25% decrease in response after 30 days of operation), with a response value of 27.98% (10 ppm), 3.82 times higher than that of pure SnS₂ (7.33%, 10 ppm). The underlying mechanisms of the enhanced electron transfer and surface adsorption at the 2D–2D interface are elucidated through both experimental results and Density Functional Theory (DFT) simulations.","PeriodicalId":425,"journal":{"name":"Sensors and Actuators B: Chemical","volume":"1 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145134242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although semiconductor-based gas sensors are highly promising for detecting toxic gases, their performance is often limited by low sensitivity and slow recovery times.

In this work, we fabricated a high-performance NO₂ gas sensor using sulfur, which is non-noble metal catalyst, supported on WO₃ microspheres via a two-step hydrothermal synthesis. The incorporation of sulfur did not alter the crystallinity or morphology of the WO₃, but it introduced additional oxygen vacancies and facilitated the spill-over effect, resulting in a sensing response more than 100 times higher than that of bare WO₃. At an operating temperature of 150°C, the sulfur-loaded WO₃ exhibited a response of nearly 500–5 ppm of NO₂, with a detection limit as low as 50 ppb.

Therefore, developing a highly sensitive and specific method for detecting CIP has become essential to ensure food safety and maintain quality control standards. However, current detection techniques remain susceptible to interference from structural analogues within the CIP family. To address this challenge and improve the specificity of CIP detection, an innovative fluorescent sensor was developed. This sensor is based on a novel Eu^III–Sc^III co-incorporated antimonotungstate hybrid [H₂N(CH₃)₂]₁₃Na₁₄H₅{[[W_0.33Sc_0.67]₂{[[W_0.33Sc_0.67]₂(Htar)O₄]₂W₆Sc₇Eu(H₂O)₅O₁₆(H₂O)₈[B<em>-β</em>-SbW₉O₃₃]₆}·77H₂O (1) synthesized via a multicomponent coordination assembly approach. Structural analysis reveals that, excluding the [B<em>-β</em>-SbW₉O₃₃]⁹⁻ fragments within the polyoxoanion of 1, seventeen metal ions are interconnected through twenty µ₂-O atoms, forming a unique seventeen-nuclear bimetallic [[W_0.33Sc_0.67]₂(Htar)O₄]₂W₆Sc₇O₁₆(H₂O)₈]¹⁹⁺ cluster. Importantly, the [Eu(H₂O)₆]³⁺ ions located on both sides of the polyoxoanion connect adjacent polyoxoanions into a one-dimensional chain-like architecture. Moreover, 1 was utilized as a fluorescent probe, exhibiting strong fluorescence emission at 614 nm upon excitation. The introduction of CIP significantly enhances the fluorescence intensity at 614 nm through the “antenna effect”, enabling highly sensitive detection. This property provides the sensor with excellent analytical performance, achieving low detection limits. This sensing platform demonstrates high practical applicability in detecting CIP in human serum and food samples, highlighting its potential for antibiotic residue monitoring in food products and pharmaceutical screening.</div></div>","PeriodicalId":425,"journal":{"name":"Sensors and Actuators B: Chemical","volume":"447 ","pages":"Article 138817"},"PeriodicalIF":3.7,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145116873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
