The effect of the temperature on the gas sensing properties of the cobalt ferrite nanoparticles (CoFe2O4 NPs) has been studied and reported. The CoFe2O4 NPs were prepared using sol-gel auto-combustion synthesis technique. The confirmation of the structural and morphological properties of the prepared CoFe2O4 NPs were carried out using various characterization technique like X-Ray diffraction analysis (XRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET). The prepared CoFe2O4 NPs were further utilized to study the gas sensing properties against various volatile compounds (VOCs) viz. ethanol, methanol, acetone, ammonia, and toluene. The CoFe2O4 NPs were found responsive to ammonia as compared to the rest of the VOCs. Afterwards, the CoFe2O4 NPs were tested at various temperature i. e. room temperature (RT- 25), 50, 100, 150, and 200°C. against ammonia. It was found that the CoFe2O4 NPs shows 76.36% response against ammonia at 100 °C. All the measurements were carried out at 100 ppm concentration of all the VOCs. Moreover, the CoFe2O4 NPs shows excellent stability of 85.76% even after 15 days. The present study will be a good lead for the further research in the field.
