摘要:

甲醇作为一种基础化工原料,是生产所需的常用溶剂,也是醇类燃料电池的常用燃料之一。然而其具有挥发性,会对人体的神经系统产生毒化作用,因此,实时监测环境中的甲醇蒸气浓度具有重要意义。本文在科研成果的基础上创新设计了一个综合实验——可穿戴智能气液双功能甲醇电化学传感器。实验过程包括无机材料合成、丝网印刷制备、仪器分析表征、电化学传感检测等内容,涵盖多门化学课程主要相关知识点,具有很好的综合性和学科前沿性。经过此实验训练,学生不仅能巩固相关化学基础知识,掌握石墨烯材料的合成与表征技能,还能了解电化学传感器的工作原理,激发学生对科学研究的兴趣。

Abstract:

Methanol, a basic chemical raw material, is a common solvent in production and one of the common fuels of alcohol fuel cells. However, it is volatile and can cause toxicity to the human nervous system. Therefore, real-time monitoring of the concentration of methanol vapor in the environment is of great significance. In this paper, a comprehensive experiment "a wearable intelligent high selectivity gas-liquid bifunctional methanol electrochemical sensor" was designed on the basis of scientific research achievements. The experiment includes inorganic material synthesis, screen printing preparation, instrumental analysis and characterization, electrochemical sensing and detection, covering the main related knowledge points of several chemistry courses, thus is very comprehensive and cutting-edge. Through this experiment, students can not only consolidate the basic knowledge of chemistry, master the synthesis and characterization skills of graphene materials, but also understand the working principle of electrochemical sensors, which greatly stimulate students' interests in scientific research.

Key words: Wearable sensors, Methanol, Electrochemistry, Vapor/liquid
