H2S Gas Sensor at Room Temperature For SnO2-CuO Thick Film
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
The SnO2 and CuO powder mixed with different ratio and heated at 8000C and then this powder is used to prepared thick films by a screen – printing technique on glass substrate. The H2S gas sensing properties, particularly the rate of response of CuO-SnO2 sensors are influenced by the CuO loadings at room temperature. XRD analysis showed that crystallite size is small (97.3nm) for 50SnO2-50CuO composition. The Sensitivity increases drastically as the expose of H2S gas for 50SnO2-50CuO sample. This sample is found to be better sensing material as regards to other.
