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 800oC, leads to a significant morphological change of NANOPARTICLES and decrement in mean particle size. RAMAN analysis revealed that the sample synthesized by NaOH has a larger ratio of Co2+/Co3+ and thus more oxygen vacancies.
