摘要：
The fabrication and testing of H2S gas sensors using nickel ferrite (NiFe(2)O4) nanoparticles and silver is presented here. The nanoparticles were prepared by chemical co-precipitation and silver was added by impregnation. The sensor response was measured at different H2S concentrations. At 200ppm H2S, results indicate a 0.18 efficiency as compared to 0.45 for NiFe2O4 and NiFe2O4-5% wt. Ag, respectively. Characterization by powder XRD indicates an average NP size of 11-39 nm. Electron Microscopy in Scanning and Transmission mode indicates agglomerates with sponge-like structure and two-dimensional slabs.
