Developing new sensor designs capable for selective gas detection and /or for sensing in harsh environments will significantly enhance the application areas of gas sensors leading to the advancements in the environmental protection, process efficiency and safety.

Sensing under harsh environments, such as offshore oil and gas platforms, refineries, liquefied natural/petroleum gas plants, is a challenging task due to the instability of semiconducting oxides and nitrides in specific process conditions. The selective detection of gases is required in several emerging fields, among them: (i) automotive applications of ceramic gas sensors (NOx, Lambdaprobe), (ii)  detection of H2 / CxHy leaks in household appliances, (ii)i monitoring gas separation efficiency in various applications, including (i) hydrogen recovery (H/ CxHy), (ii) natural gas dehydration (CxHy / H2O), (iii) raw natural gas purification (CH/ C3H8, CH/ C4H10), (iv) detection of NOx, CxHy, SO2, and CO in exhaust gases, and (v) detection of CO2, H2O and toxic gases for air quality monitoring.

Topics

  • Exploring carbon-based and hybrid organic-inorganic ink-jet printed materials with low power consumption for room-temperature gas detection
  • Enhancement of the selectivity of chemiresistors and the improvement of their stability in harsh environments through Si-containing ceramic filters derived from polymers
  • In-situ and operando characterization for probing the gas sensing mechanisms
