“…The evolution of rhombohedral LaCoO 3 is in good agreement with the literature, where the transition was also reported for x � 0.40 in LaFe 1À x Co x O 3 . [33] In addition, for x > 0.40, a minor amount of Fe 3-x Co x O 4 spinel phase was formed. A possible reason for this is cation segregation upon LDH formation.…”

“…For crystallization of the material, thermal treatment of at least 500 • C is necessary [1]. Perovskite oxides with lanthanum (La) as the A-site cation and cobalt (Co) and iron (Fe) as the B-site cations have been synthesized via thermal decomposition of propionates [21], the Pechini method [22], or the sol-gel approach [23]. The synthesis of LaFe x Co 1−x O 3 via co-precipitation assisted by microwaves has been reported [24].…”

“…In this sense, the sol-gel method results in smaller grain sizes than the solid-state reaction method. In fact, the Pechini method is known for delivering homogeneous solutions with a great control of composition and production of ultrafine nanometric oxides [70,71], which makes this method very attractive for recent developments and future trends in the field of Ni/MH batteries (see ''Drawbacks and future challenges''). Compared with the solid-state reaction, the glycine-nitrate route and the solgel technique require lower calcination temperatures and reduced calcination times to yield pure crystals of perovskite-type oxides.…”
