Abstract
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.
