Abstract
LaFe0.6Co0.4O3 perovskite is a candidate material for a carbon monoxide gas sensor. The synthesis of cobalt doped lanthanum ferrite perovskite nanoparticles via chemical route using ammonium hydroxide NH4OH and sodium hydroxide NaOH as the precipitation agent and calcination at different temperatures is reported. Presence of crystallized particles in orthorhombic lattice was confirmed with phase analysis using X-ray diffraction XRD. Field emission scanning electron microscopy FESEM observations revealed that smaller mean particle size obtained by using NH4OH precipitant. Lowering the calcination temperature, from 900 to 800°C, leads to a significant morphological change of nanoparticles and decrement in mean particle size.
