Abstract

Two types of H₂S gas sensors were fabricated based on zinc and copper ferrites’ nanoparticles (NPs) in organic polymer. The ferrite nanoparticles were synthesized using the co-precipitation method. Polymer solutions of poly-vinyl-alcohol (PVA) and glycerol ionic liquid (IL) were prepared and doped with the ferrite NPs, and then a solution casting method was used to convert these solutions into membranes. These membranes (PVA + IL + ZnFe₂O₄and PVA + IL + CuFe₂O₄) were tested against H₂S gas with reference to time at different temperatures and H₂S gas concentrations. Their conductance response showed high sensitivity towards H₂S gas at low temperature of 40 °C, and H₂S concentrations of 10 ppm and 25 ppm for ZnFe₂O₄and CuFe₂O₄based sensors, respectively. Both sensors showed a fast response time around 20 s. Moreover, ZnFe₂O₄NPs based sensor showed more reversible behavior compared with CuFe₂O₄NPs based sensor, and both sensors were selective toward H₂S gas. Overall, the sensors were easy and cheap to manufacture, thus, they have potential to be used in industrial fields.
