Abstract

Hexanal detection is essential for real-time monitoring of oil oxidation stability and evaluating health impact. Nevertheless, accurately monitoring hexanal levels in the presence of other volatile organic compounds (VOCs) remains a significant challenge. In this article, we present an In2O3/SnO2 composite-based electrochemical gas sensor that offers excellent selectivity for hexanal over other tested VOCs, such as styrene, acetone, and n-hexane, and featured a remarkably low detection limit of approximately 50 parts per billion (ppb). In addition, a gas sensing device that integrated the aforementioned electrochemical hexanal sensor with blockchain technology was developed to facilitate remote monitoring of hexanal variations. In particular, shuffling technology and digital signatures were utilized to bolster the security of data transmission and access. It turns out that the developed sensing device demonstrated impressive performance in both sensing accuracy and data security, highlighting its potential as a promising solution for remote hexanal monitoring.

基于ysz的In₂O₃/SnO₂高选择性跟踪己醛的电化学传感装置

己醛检测对于实时监测油的氧化稳定性和评估对健康的影响至关重要。然而，在其他挥发性有机化合物（VOCs）存在的情况下，准确监测己醛水平仍然是一个重大挑战。在本文中，我们提出了一种基于In2O3/SnO2复合材料的电化学气体传感器，该传感器对己醛的选择性优于其他测试的voc，如苯乙烯，丙酮和正己烷，并且具有非常低的检测限，约为十亿分之50 （ppb）。此外，开发了一种将上述电化学己醛传感器与区块链技术相结合的气体传感装置，以方便远程监测己醛的变化。特别是，利用变换技术和数字签名来增强数据传输和访问的安全性。结果表明，所开发的传感装置在传感精度和数据安全性方面都表现出令人印象深刻的性能，突出了其作为远程己醛监测解决方案的潜力。
