摘要

采用水热法制备了基于CeO2/NiO复合材料的高性能氨气(NH3)传感器．实验结果表明，CeO2/NiO复合材料可显著提高NiO基NH3传感器的气敏性能．这一改进主要源于材料表面氧空位(Ov)、化学吸附氧(Oc)的增加，以及Ni3+在CeO2/NiO表面的比例增加．CeO2/NiO传感器对NH3具有较高响应，在NH3浓度为5×10-6mL/m3时，其响应/恢复时间为1.8 s/0.9 s，理论最低检测极限为98.651×10-9mL/m3．此外，该传感器已成功应用于胃幽门螺旋杆菌感染的模拟检测，显示了其在生物医学诊断中的重要研究价值和潜在应用前景．

Abstract

A high-performance ammonia(NH3) sensor is prepared based on CeO2/NiO composite

using a hydrothermal method.Experimental findings confirm that the CeO2/NiO composite significantly enhances the performance of the NiO-based NH3 sensor.This improvement is primarily due to the increase in oxygen vacancies(Ov)

chemically adsorbed oxygen(Oc)

and the proportion of Ni3+ on the surface of the CeO2/NiO.The CeO2/NiO sensor shows a high response to NH3

exhibiting response/recovery times of 1.8 s/0.9 s at the NH3 concentration of 5×10-6 mL/m3

with the theoretical lowest detection limit of98.651×10-9 mL/m3.Additionally

the CeO2/NiO sensor has been successfully applied in the simulated detection of Helicobacter pylori infection

highlighting its significant research value and potential application prospects in biomedical diagnostics.
