Effect of ferric ion [Fe3+] and [Fe2+] on SO2 adsorption ability of γ-Fe2O3 nanoparticles for mass-type gas sensors

The sensing material plays a very important role in determining the sensing properties of a gas sensor. In order to synthesise the sensing material, the precursors have a large effect on the properties of the sensing material. In this study, three types of γ-Fe2O3 nanoparticles were prepared with di...
