Abstract

Electrochemical sensors for Volatile Organic Compound (VOCs) based on commercial YSZ layers were fabricated using Pt and SmFeO₃ perovskite oxide as electrodes, both exposed to the same gas environment. Pt was sputtered on YSZ layers while SmFeO₃ p-type semiconducting oxide was deposited by electrophoretic deposition (EPD). Nanometric SmFeO₃ oxide powders were selected because they have already shown good sensing performance in semiconducting sensors for oxidizing gases such as NO₂ and ozone, and reducing gases, such as VOCs, Potentiometric measurements were performed under exposure to different concentrations of VOCs such as: methyl ethyl ketone (MEK), ethanol (EtOH) and acetic acid (AA). The best gas sensing response was obtained at 400°C.
