Abstract

The study compares three metal oxide semiconductor (MOS) sensors based on diverse WO₃nanostructures for ammonia detection: nanoparticles, nanoflakes, and WO₃-x nanoflowers. Among them, WO₃-x nanoflowers exhibited the highest response and low-power operation (300°C). The results highlight the crucial role of nanostructure morphology and lead to further optimization to enhance response in humid environments for selective ammonia sensor.
