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

Figure 4

H2-TPR profiles of La1−xCexCoO3 (a) and La1−xCexMnO3 (b) perovskites ( = 0, 0.2, and 0.4). The reduction peaks shifted to the lower temperature, indicating that Ce4+ insertion increased the catalyst reducibility.
