In this study, we fabricated zinc-substituted magnesium ferrite (MgFe2O4) (ZMF) nanoparticles with the general formula ZnxMg1−xFe2O4 (x = 0.00–0.75) using a surfactant-assisted co-precipitation method and evaluated their H2S gas-sensing performance. Fourier-transform infrared and X-ray diffraction analysis results reveal the formation of a cubic spinel ferrite structure. The effect of zinc substitution on the physico-chemical properties of MgFe2O4 was studied and is discussed herein. The polycrystalline ZMF nanoparticles are magnetic and showed advantageous gas-sensing performance, the results of which reveal that they are sensitive to and selective for hydrogen sulfide (H2S) gas. The ZMF gas sensors exhibited good sensing of various test gases/vapors, such as H2S, H2, Cl2, carbon dioxide, liquid petroleum gas, ammonia, and ethanol while working at room temperature to 400 °C. The Zn0.5Mg0.5Fe2O4 composition produced the highest response toward 10 ppm H2S gas at 400 °C operating temperature.
