Abstract

The present work explores ethanol and acetone sensing performance of atmospheric plasma sprayed 25 wt.% WO₃-75 wt.% SnO₂ coating deposited on alumina substrate. Sensing characterization of the coating was tested using a homemade static chamber in the presence of ethanol and acetone. Sensor response characteristics were also obtained by varying concentration of test vapour. Concentration dependent response transients were modeled using Langmuir-Hinshelwood isotherm to estimate characteristic time constant for ethanol and acetone sensing.
