Investigation the sensor mechanism of In2O3 towards VOCs by operando DRIFT measurements

01/03/2024 to 28/02/2026

The rapid, reliable and selective determination of air pollutants in the smallest concentrations is essential for human health concern and environmental monitoring. In2O3 is a promising material for gas sensors application, but to date less studied than others n-type semiconductor metal oxides. The aim of this project is to study in detail the sensory properties of In2O3 towards three different classes of volatile organic compounds in dry and humid air. In order to get a complete picture of the In2O3 sensory response mechanism, it is planned to use diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy measurements in combination with density functional theory (DFT) calculations.
