Abstract

The high surface area and tunable electronic characteristics of 2D layered tin sulfide (SnS) materials make them promise for gas sensing applications. Here, potassium-intercalated SnS (K-SnS) nanorods prepared for the nitrous oxide (N₂O) detection. Rietveld refinement confirms structural changes, and Kelvin probe force microscopy revealed tuning of work function, suggesting a strong K-SnS interaction. Chemi-resistive measurements showed that K-SnS was more sensitive than pristine SnS, which was explained by effective charge transfer. The suggested sensing method shows that K-SnS is a good option for detecting N₂O at room temperature.

用功函数调谐的K+嵌入SnS纳米棒室温ppb检测氧化亚氮

二维层状硫化锡（SnS）材料的高表面积和可调电子特性使其有望用于气敏应用。在这里，钾嵌入SnS （K-SnS）纳米棒制备用于检测一氧化二氮（N2O）。Rietveld细化证实了结构的变化，开尔文探针力显微镜显示了功函数的调整，表明了强烈的K-SnS相互作用。化学电阻测量表明，K-SnS比原始SnS更敏感，这可以用有效电荷转移来解释。所提出的传感方法表明，K-SnS是在室温下检测N2O的良好选择。

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
