| description | <p>Spinel ferrite nanoparticles can be easily retrieved and utilized for multiple cycles due to their magnetic properties. In this work, nanoparticles of a Zn<sub>x</sub>Cu<sub>1-x</sub>Fe<sub>2</sub>O<sub>4</sub> composition were synthesized by employing a sol–gel auto-combustion technique. The morphology, composition, and crystal structure were examined using scanning electron microscopy, infrared spectroscopy, and X-ray diffraction. The produced nanoparticles are in the range of 30–70 nm and manifest spinel cubic structure. The nanoparticles were tested for their sensitivity to H<sub>2</sub> and H<sub>2</sub>S gases, and the Cu-based spinel ferrite nanoparticles were found the most sensitive and selective to H<sub>2</sub>S gas. Their enhanced response to H<sub>2</sub>S gas was attributed to the production of metallic CuFeS<sub>2</sub> that manifest higher electrical conductivity as compared with CuFe<sub>2</sub>O<sub>4</sub>. The fabricated sensors are functional at low temperatures, and consequently, they need low operational power. They are also simple to fabricate with appropriate cost.</p> <h2>Other Information</h2> <p>Published in: Applied Physics A<br> License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br> See article on publisher's website: <a href="http://dx.doi.org/10.1007/s00339-020-03661-9" target="_blank">http://dx.doi.org/10.1007/s00339-020-03661-9</a></p> |
