Real-time sulfur dioxide (SO2) monitoring is essential to mitigate its severe health and environmental impacts while ensuring compliance with industrial safety emission regulations. Two-dimensional MoS2 stands out as a promising material for developing low-temperature-operated gas sensors due exceptionally high surface-to-volume ratio ease of surface functionalization. However, the SO2 level faces challenges, including limited selectivity, sensitivity, detection range, operating temperatures (200-600 °C) or external light source requirements. To address these issues, we present highly sensitive sensor based on Fe2O3 nanoparticle-functionalized vertically aligned nanostructure material, which fabricated using scalable sputtering process. The Fe2O3-MoS2 exhibits broad range from 100 ppb ppm, theoretical limit around 22.8 ppb. When exposed 5 ppm SO2, achieves response 32.2%, recovery times approximately 104 141 s, respectively. demonstrated impressive sensitivity (4.9%/ppm) concentration in 0.1 coupled excellent reproducibility stability at 150 °C. This enhanced performance attributed catalytic effect modulation heterojunction barrier interface. study introduces scalable, reliable, stable sensor, paves way energy-efficient miniaturized sensors.
