摘要

氯（Cl2）具有剧毒和刺激性，即使浓度很低也会对人体造成不可逆转的伤害。因此，开发一种对痕量 Cl2 泄漏高度敏感的传感器意义重大。在这项研究中，利用廉价的花生壳作为生物模板，通过简单的三步法制备了掺K氧化铟（K-In2O3）的多孔板。表征结果表明，由花生壳生物模板制备的 K-In2O3 具有多孔片状微结构，所获得的材料具有丰富的氧空位和高比表面积。气体传感测试表明，K-In2O3 多孔薄片传感器对低浓度 Cl2 具有出色的灵敏度。

The use of peanut shells as a bio-template to prepare K-doped In2O3 porous sheets for chlorine detection†

Chlorine (Cl₂) 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 Cl₂ leakage. In this work, inexpensive peanut shells are used as a biological template to prepare K-doped indium oxide (K-In₂O₃) porous sheets through a simple three-step process. The characterization results reveal the porous sheet microstructure of the prepared K-In₂O₃ 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-In₂O₃ porous sheet sensor exhibits excellent sensitivity to low concentrations of Cl₂.
