摘要

以Cr2O3- Fe2O3纳米颗粒（比例为2:1,1:1和1:2）为原料，采用光解法制备了H2S气体传感器。利用XRD、EDx和SEM对样品的化学成分和微观结构进行了表征。在100°C到250°C的不同工作温度下，测试了传感器的气敏性能。结果表明，在1:2的比例下，传感器对H2S气体的检测效果最佳。此外，讨论还围绕传感器对H2S的传感机制展开。

H₂S Sensor Based on Cr₂O₃-ɣFe₂O₃ Nanoparticles Synthesized via Photolysis Method.

A H₂S gas sensor has been manufactured using Cr₂O₃-ɣFe₂O₃ 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 H₂S gas at a ratio of 1:2. Furthermore, the discussion revolved around the sensor's sensing mechanism specifically for H₂S.
