Evaluation of Cox Fe3-x O 4 cobaltites as ethanol sensing material
Abstract
CoxFe3-xO4 oxide powders were synthesised by an oxalate decomposition process. Microstructural analysis like X-ray fluorescence spectroscopy confirmed the composition of the prepared powders. These powders were then deposited onto alumina substrates in order to study their response under ethanol gas pulses. The gas sensing experiment was carried by a defined test protocol and several characteristics were tracked. Results showed a direct link between the proportion of cobalt and gas sensing performances.
