Abstract
The aim of this work was to design and test an array of sensors based on nanocrystalline of TiO2:Cr (0.1-10 at.% Cr) for reliable and reproducible gas detection. Thermally modulated responses of metal oxide nanosensors to hydrogen, methane and propane (0 - 3000 ppm) at various humidity levels (up to 75%RH) were studied. The sensors operated upon sinusoidal temperature profile over a temperature range of 240 - 300°C. The dynamic responses upon target gas exposure were recorded, processed and analyzed. The change of the conductivity type from n-type to p-type was observed at 1 at.% Cr doping. The TiO2:Cr (5 at.% Cr) nanosensor was found to exhibit the highest response to hydrogen. © 2014 Published by Elsevier Ltd.
