CO Oxidation Capabilities of La- and Nd-Based Perovskites

Catalytic tests to assess the performance of mixed perovskite-type oxides (La0.9Ca0.1FeO3-δ, La0.6Ca0.4FeO3-δ, Nd0.9Ca0.1FeO3-δ, Nd0.6Ca0.4FeO3-δ, Nd0.6Ca0.4Fe0.9Co0.1O3-δ, Nd0.6Ca0.4Fe0.97Ni0.03O3-δ, and LSF) with respect CO oxidation are presented as well characterization materials by XRD SEM. Perovskites a highly versatile class due their flexible composition ability incorporate dopants easily. is widely used “probe reaction” for heterogeneous catalysts. In this study, it demonstrated how tuning catalyst material (choice A-site cation, B-site doping) greatly influences activity. Changing cation Nd3+ or increasing concentration Ca2+ dopant improves catalyst. Additional doping (e.g., Co) affects well—in case Co-doping shifting ignition temperature lower temperatures. Thus, perovskites offer an interesting approach intelligent design specific properties towards desired applications.
