“…ZnO and ZnO/ZnFe2O4 structures were formed on sensor platforms with NiCr/Ni/Au interdigitated electrodes. ZnO nanowires were produced by hydrothermal synthesis described in details in [10,11]. First, seed layers consisting of zinc oxide nanoparticles were formed by spin-coating (3 cycles) of zinc acetate dehydrate aqueous solution (5 mM).…”

Currently, new nanostructured materials based on composite metal oxides is of great interest for the development of gas sensors with improved functional characteristics. In this work, zinc oxide nanowires were synthesized by hydrothermal method. Hierarchical ZnO/ZnFe2O4 nanostructures were obtained by immersion of zinc oxide layers in ferrous sulphate aqueous solution. The mechanism of zinc ferrite formation during the interaction of zinc oxide with iron sulphate is considered. The crystal structure of ZnO and ZnO/ZnFe2O4 were studied by Raman spectroscopy. The sensitivity of ZnO and ZnO/ZnFe2O4 nanostructures to isopropyl alcohol vapors was analyzed. It was shown that there is an optimal concentration of ferrous sulphate used to modify zinc oxide nanowires and synthesize ZnO/ZnFe2O4 composite nanostructures.
