Conclusion:
LaCoO3 perovskite nanoparticles can be produced by
sol-gel auto-combustion, using a single step method. This method is
low-cost, time-efficient and does not require advanced equipment for the
production process. Investigation of the lattice structure, morphology,
particle size by XRD, SEM and PSA analysis methods show that particles
are uniform in shape and size and these characteristics play important
roles in the application of nanoparticles as the catalyst and cause
uniformity in the properties of the catalyst. The production of uniform
size nanoparticles using this method is the result of the use of
surfactants in the synthesis process. The results confirm the successful
synthesis of LaCoO3 nanoparticles which are in a
spherical shape and below 100 nm in size.
