Abstract

Chlorine (Cl) is highly toxic and pungent, and can cause irreversible harm to humans even at low concentrations. Therefore, it is significant to develop a sensor that is highly sensitive to trace amounts of Cl leakage. In this work, inexpensive peanut shells are used as a biological template to prepare K-doped indium oxide (K-InO) porous sheets through a simple three-step process. The characterization results reveal the porous sheet microstructure of the prepared K-InO derived from the peanut shell bio-template, and the obtained material possesses rich oxygen vacancies and a high specific surface area. Gas-sensing tests demonstrate that the K-InO porous sheet sensor exhibits excellent sensitivity to low concentrations of Cl.

摘要

氯（Cl）毒性很强且具有刺激性，即使在低浓度下也会对人体造成不可逆转的伤害。因此，开发一种对微量Cl泄漏高度敏感的传感器具有重要意义。在这项工作中，廉价的花生壳被用作生物模板，通过简单的三步工艺制备了K掺杂氧化铟（K-InO）多孔片。表征结果揭示了由花生壳生物模板衍生制备的K-InO的多孔片微观结构，且所获得的材料具有丰富的氧空位和高比表面积。气敏测试表明，K-InO多孔片传感器对低浓度的Cl表现出优异的灵敏度。
