Synthesis and Characterization of Ag Doped LaCoO₃ Nanowire Sputter-Deposited Coatings as Heavy Hydrocarbon Sensors

Abstract:

In this paper, we investigate the feasibility of La_1-xAg_xCoO_3-α nanowires by reactive magnetron sputtering. After a short description of the experimental and hydrocarbon sensing bench devices, a first part will be dedicated to the chemical, microstructural and structural characterization (SEM, XRD,...) of the coatings. As deposited coatings are amorphous and a post heat-treatment under air at 873 K is necessary to crystallise them in the perovskite structure. Finally, the performance as dodecane-sensors of these coatings with amorphous and crystalline structures will be discussed depending on dodecane concentrations and sensitive surfaces temperature and will be compared to those of La_0.40Sr_0.15Ag_0.45CoO_3-α nanowires.
