Lanthanum-Based Perovskite-Type Oxides La_1−xCe_xBO₃ (B = Mn and Co) as Catalysts: Synthesis and Characterization

Table 2

XRD and BET analysis results of and (x = 0, 0.2, and 0.4) perovskites. Lattice parameters enlarged due to Ce substitution and the crystallite size decreased with the increase of substitution concentration.
