Abstract
Hydrogen sulfide (H₂S) is a hazardous gas that necessitates reliable detection in industrial and environ-mental settings. Hexagonal tungsten oxide (h-WO₃) has gained attention as a promising sensing mate-rial due to its high surface reactivity and structural stability. This study presents the hydrothermal syn-thesis of h-WO₃, characterized by XRD, Raman spectroscopy, and SEM. The material exhibited out-standing selectivity and sensitivity toward H₂S, attributed to its porous structure and surface chemistry. These findings underscore the potential of h-WO₃ for effective H₂S gas sensing applications.
