Abstract

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

摘要

通过一种经济高效且简单的光解方法制备了用CrO修饰的MnO，并将其用作HS气体传感器。该纳米复合材料在200°C下对HS气体表现出优异的化学传感性能，灵敏度达到89.93。提出的传感机制突出了MnO和CrO在气体检测中的协同作用。这项研究强调了MnO-CrO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一种可靠且高效的解决方案。
