Synthesis and Gas‐Sensing Performances of Mn <sub>3</sub> O <sub>4</sub> ‐Decorated Cr <sub>2</sub> O <sub>3</sub> Nanoparticle for H <sub>2</sub> S Detection

Mn<sub>3</sub>O<sub>4</sub> decorated with Cr<sub>2</sub>O<sub>3</sub> was prepared via a cost-effective and straightforward photolysis method and utilized as an H<sub>2</sub>S gas sensor. The nanocomposite exhibited excellent chemical sensing properties toward H<sub>2</sub>S gas at 200°C, achieving a sensitivity of 89.93. A proposed sensing mechanism highlights the synergistic roles of Mn<sub>3</sub>O<sub>4</sub> and Cr<sub>2</sub>O<sub>3</sub> in gas detection. This study underscores the potential of Mn<sub>3</sub>O<sub>4</sub>-Cr<sub>2</sub>O<sub>3</sub> composites in industrial and environmental monitoring applications, offering a reliable and efficient solution for detecting hazardous gases.
