In
this study, CuFe2O4 nanoparticles were synthesized by
co-precipitation method using oleic acid as surfactant under different growth
temperatures. The samples were calcined at different temperatures to find their
formation phase. The particles were studied
using XRD and SEM. XRD results showed the
tetragonal structure of the samples. SEM analysis showed that the influence of
synthesis temperature and calcinations temperature on morphology and mean
nanoparticles size. Copper ferrite nanoparticles and potassium bromide
particles were used as metal oxide semiconductor gas sensor for detection of
ethanol gas. Different voltages were applied to the sensor and the optimum voltage of
the sensor was
determined. Finally, the response of the sensor was calculated according to the
various concentration of ethanol gas
and its curve was drawn in terms of the gas
concentration
