Lanthanum-Based Perovskite-Type Oxides La1−xCexBO3 (B = Mn and Co) as Catalysts: Synthesis and Characterization

Figure 1

FT-IR spectra of the La1−xCexCoO3 (a) and La1−xCexMnO3 (b) perovskites ( = 0, 0.2, and 0.4). The most important vibration band around 600 cm−1 appears sharper for = 0.2 suggesting the perovskite with more symmetrical structure.
