Industrially Produced Fe- and Mn-Based Perovskites: Effect of Synthesis on Reactivity in Three-Way Catalysis: Part 1

La0.6Ca0.2Fe0.8Cu0.2O3, undoped (LF) and Ca, Cu-doped (LCFC), powders, obtained by different industrial procedures, are compared to evaluate reproducibility scale-up in synthetic approaches: flame spray pyrolysis (FSP) coprecipitation (COP). Also the effects of varying composition (doping) FSP process variability considered as comparative studies on morphological, crystallographic, redox compositional properties, functional activity. A model reaction (CO + NO) reactions with an automotive exhaust mixture were carried out. Unexpected results effectiveness doping for catalytic activity emerged. Samples same compositions proved be significantly affected synthesis, within process. The LCFC COP is comparable analogue, at stoichiometric conditions, notwithstanding differences highlighted characterization. In oxygen-deficient mixture, LCFC-COP yields higher NO reduction CO oxidation than LCFC-FSP. absence Ca lattice was unexpectedly beneficial. must carefully checked large-scale production.
