Abstract
We investigate H2S gas sensors based on spinel ferrite CuFe2O4 nanoparticles prepared by the co-precipitation method. This technique is an efficient and fast technique to produce nanoparticles. Furthermore, those nanoparticles are metal-oxide nanoparticles with magnetic properties that enable their retrieval and reuse for mutable times and applications. The produced nanoparticles are pressed in a form of disc, and placed between two electrical electrodes, with the top electrode with a grid structure to enable gas exposure. The study includes investigations of crystal structure, composition, morphology, and charge transport. The results revel that the produced nanoparticles are sensitive and selective to H2S which indicate their potential to be used for practical applications.
