摘要

采用成本效益高、操作简单的光解方法制备了Cr2O3修饰的Mn3O4，并将其用作H2S气体传感器。该纳米复合材料在200℃时对H2S气体表现出优异的化学传感性能，灵敏度达到89.93。提出了一种传感机制，强调了Mn3O4和Cr2O3在气体检测中的协同作用。该研究强调了Mn3O4-Cr2O3复合材料在工业和环境监测应用中的潜力，为检测有害气体提供了可靠和高效的解决方案。

Synthesis and Gas-Sensing Performances of Mn₃O₄-Decorated Cr₂O₃ Nanoparticle for H₂S Detection.

Mn₃O₄ decorated with Cr₂O₃ was prepared via a cost-effective and straightforward photolysis method and utilized as an H₂S gas sensor. The nanocomposite exhibited excellent chemical sensing properties toward H₂S gas at 200°C, achieving a sensitivity of 89.93. A proposed sensing mechanism highlights the synergistic roles of Mn₃O₄ and Cr₂O₃ in gas detection. This study underscores the potential of Mn₃O₄-Cr₂O₃ composites in industrial and environmental monitoring applications, offering a reliable and efficient solution for detecting hazardous gases.
