PROJECT TITLE :
Highly Sensitive, Room Temperature Methane Gas Sensor Based on Lead Sulfide Colloidal Nanocrystals
A solid-state methane gas sensor primarily based on PbS colloidal nanocrystals has been fabricated and tested for the primary time. PbS nanoparticles have been synthesized throughout an all-chemical method and its X-ray diffraction (XRD) pattern has been analyzed to verify the quality and estimate the particle size of created nano-powder. TEM microscopy and size estimation by XRD analysis each make sure the assembly of forty-nm PbS nanoparticles. The sensor was fabricated by the drop casting methodology on interdigitated electrodes and tested at completely different conditions. The most effective achieved sensitivity was 47.half-dozen% for five% methane concentration at room temperature. A comprehensive discussion on sensing mechanism, temperature dependence, and sensor's benefits is additionally provided during this paper. The sensor has the advantage of space temperature detection and being highly sensitive. Moreover, the sensor's detection range is one%–5% which is of superior importance in air quality monitoring and safety control systems in industrial environments to forestall suffocation and explosion.
