Research output: Contribution to journalArticle


The gas sensing properties of nickel ferrite (NiFe2O4) and nickel oxide (NiO) nanoparticles prepared by a levitation-jet synthesis (LJS) method are reported. These have been compared to the gas sensing properties of a NiO sensor, prepared using a commercially-sourced powder. The microstructure, surface area, particle size and morphology varied widely across the sensors fabricated. Gases included ethanol, acetone, carbon monoxide, toluene and nitrogen dioxide and the gas response of the sensors was investigated at different operating temperatures. The NiFe2O4 sensor presented most promise as a gas sensor, with outstanding sensor sensitivity towards ppb concentrations of NO2. This sensor was also remarkably sensitive to ethanol and, to a greater or lesser degree, towards acetone and toluene gases. In general, sensors were poorly responsive to the carbon monoxide concentrations tested. This study is one of the first reports of using LJS-based powders for gas sensing applications for the detection of environmentally-relevant gases.
