Gas sensors for acetone detection have received considerable attention because has a significant influence on both the environment and human health, e.g., it is flammable toxic may be related to blood glucose levels. However, achieving high sensitivity selectivity at low concentrations still great challenge date. Here, we report unique chemiresistive gas sensor detection, which composed of In2O3 nanofibers loaded with porous Co-based zeolitic imidazolate framework (ZIF-67)-derived Co3O4 cage prepared by simple electrospinning solvothermal methods. The ZIF-67-derived oxide cage/nanofiber Co3O4/In2O3 heterostructure abundant reversible active adsorption/reaction sites type-I heterojunction, resulting in an ultrasensitive response 954–50 ppm 300 °C. In addition, demonstrates limit 18.8 ppb, fast time 4 s, good repeatability, acceptable humidity interference, long-term stability. With such excellent sensing performance acetone, our could potentially applied environmental monitoring early diagnosis diabetes.

Опубликована: Фев. 7, 2024

Abstract The development of a cost‐effective, ultra‐selective, and room temperature gas sensor is the need an hour, owing to rapid industrialization. Here, new 2D semiconducting Cu(I) coordination polymer (CP) with 1,4‐di(1H‐1,2,4‐triazol‐1‐yl)benzene (1,4‐TzB) ligand reported. CP1 consists Cu 2 I secondary building unit bridged by 1,4‐TzB, has high stability as well properties. chemiresistive sensor, developed facile drop‐casting method derived from CP1, demonstrates response value 66.7 at 100 ppm on methanol exposure, accompanied swift transient (response recovery time 17.5 34.2 s, respectively) behavior. In addition, displays ultra‐high selectivity toward over other volatile organic compounds , boasting LOD LOQ values 1.22 4.02 ppb, respectively. CP found be state‐of‐the‐art sensitivity temperature.
