Nanostructured Ferrite Based Electronic Nose Sensitive to Ammonia at Room Temperature

Nanostructured Ferrite Based Electronic Nose Sensitive to Ammonia at Room Temperature

Manganese and Nickel doped Zinc Ferrite powder (Mn0.3Ni0.3Zn0.4Fe2O4) was synthesized by autocatalytic thermal decomposition technique. The average crystallite size in the material powder was found to be of 10 – 13 nm. Characterization techniques such as X-Ray diffraction studies, Transmission elect...
