ZnO-碳纤维异质结构的乙醇敏感特性研究
|
Abstract:
呼气中痕量乙醇的低浓度、高灵敏度的快速监测对于非酒精性脂肪肝疾病的初步诊断具有重要意义。健康人体口腔呼出的乙醇浓度低于380 ppb，而中毒和脂肪肝疾病患者口腔呼出乙醇的浓度高达2300 ppb。本工作旨在通过准二维电化学沉积技术构建具有清晰异质界面的ZnO-碳纤维异质结构，通过乙醇气体的吸附来改变接触界面特性引起气敏材料电阻的变化，从而产生变化的电流。选用高导电性的碳纤维与ZnO构建异质结结构，有助于实现低浓度乙醇气体的检测。实验数据表明，该乙醇气体传感器表现出优异的性能，对100 ppb乙醇响应度为460，检测浓度范围为100 ppb~10 ppm，能够满足人体口腔呼出气体中乙醇的检测需求。本工作表明，合理设计的ZnO-碳纤维异质结构是一种具有良好应用前景的乙醇传感器。
Low-concentration, high-sensitivity rapid monitoring of trace ethanol in the breath is important for the initial diagnosis of nonalcoholic fatty liver disease. Healthy humans have oral exhaled ethanol concentrations below 380 ppb, while patients with poisoning and fatty liver disease have oral exhaled ethanol concentrations of up to 2300 ppb. This work aims to construct a ZnO-carbon fiber heterostructure with a clear heterointerface by quasi-two-dimensional electrochemical deposition technology, and change the contact interface characteristics by the adsorption of ethanol gas, causing the change of resistance of the gas-sensitive material, thereby generating a changing current. The selection of highly conductive carbon fiber and ZnO to construct a heterojunction structure is helpful for the detection of low concentrations of ethanol gas. The experimental data show that the ethanol gas sensor shows excellent performance, with a responsivity of 460 for 100 ppb ethanol and a detection concentration range of 100 ppb to 10 ppm, which can meet the detection needs of ethanol in human oral exhaled gas. This work shows that the rationally designed ZnO-carbon fiber heterostructure is an ethanol sensor with good application prospects.
