Abstract

A HS gas sensor has been manufactured using CrO-ɣFeO nanoparticles with ratios of (2:1, 1:1, and 1:2), using the photolysis method. The chemical composition and microstructure of the resulting samples were characterized using XRD, EDx, and SEM. The sensor's gas-sensing performance was examined at various operating temperatures ranging from 100°C to 250°C. The results demonstrated that the sensor had optimal response in detecting HS gas at a ratio of 1:2. Furthermore, the discussion revolved around the sensor's sensing mechanism specifically for HS.

摘要

采用光解方法，利用比例为（2:1、1:1和1:2）的CrO-γFeO纳米颗粒制造了一种HS气体传感器。使用X射线衍射（XRD）、能谱仪（EDx）和扫描电子显微镜（SEM）对所得样品的化学成分和微观结构进行了表征。在100°C至250°C的各种操作温度下检查了该传感器的气敏性能。结果表明，该传感器在检测比例为1:2的HS气体时具有最佳响应。此外，讨论围绕该传感器对HS的传感机制展开。
