Lead Phosphate Material for Exclusive Detection of Hydrogen Sulfide Gas
Efficient gas sensors that can accurately detect and identify hydrogen sulfide are essential for various practical applications. Conventional resistive sensors often lack the necessary selectivity, which hampers timely and effective H<sub>2</sub>S detection. This study presents lead phosphate-based gas sensors specifically designed for H<sub>2</sub>S detection, which effectively eliminate interference effects. Notably, altering the metal element did not compromise the sensor's exceptional selectivity. The sensing mechanism behind this excellent selectivity is explained. The findings demonstrate the potential for developing high-performance phosphate-based gas sensors for use under ambient conditions and offer a strategic reference for designing highly selective sensors.
