Abstract :

In this study cadmium doped nickel copper ferrite Ni0.5Cu0.5Fe2O4 (cd doped) nanoparticles with spinel structure were synthesized using co-precipitation method. The nanoparticles were employed as a gas sensing material. X-ray diffraction (XRD), X-ray fluorescence (XRF) and transmission electron microscopy (TEM) techniques were used to characterize the nanoparticles structure. The sensing behavior of the nanoparticles was examined in the presence of different gases including. Acetone, acetonitrile, acrylonitrile, formamide, caron tetrachloride, vinyl acetate, ethanol, ammonia, and methanol. The characterization process was performed for a concentration of a 200 ppm and within a temperature interval from 50 ˚C to 300 ˚C and the best sensing behavior was found to be at 200 ˚C. Furthermore, various concentrations of acetonitrile gas at 200 ˚C within a concentration interval of 20 to 200 ppm were tested and it is found that the higher concentrations will result in a better response.
