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 H2S detection. This study presents lead phosphate-based gas sensors specifically designed for H2S 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.
期刊介绍：
ACS Sensors is a peer-reviewed research journal that focuses on the dissemination of new and original knowledge in the field of sensor science, particularly those that selectively sense chemical or biological species or processes. The journal covers a broad range of topics, including but not limited to biosensors, chemical sensors, gas sensors, intracellular sensors, single molecule sensors, cell chips, and microfluidic devices. It aims to publish articles that address conceptual advances in sensing technology applicable to various types of analytes or application papers that report on the use of existing sensing concepts in new ways or for new analytes.
