Characterization and activity of perovskite catalysts for autothermal reforming of dodecane

Surface reconstructions of LaCo1−xFexO3 at high temperature during N2O decomposition in realistic exhaust gas composition: Impact on the catalytic properties

“…An additional contribution with remarkably different isomer shift (IS = 0.036 mm/s) was also introduced to the spectrum fitting. This component has been attributed to Fe 4+ ions and is consistent with previous findings [33,38]. As earlier discussed from XPS data, Co 2+ species might exist at high iron content.…”

The Effect of Water on the 2‐Propanol Oxidation Activity of Co‐Substituted LaFe1−xCoxO3 Perovskites

“…0.47 mm s À 1 relative to α-Fe at room temperature, characteristic of the Fe 3 + state. [38] No further additional spectral features were observable that deviate from the hyperfine field or isomer shift of the above discussed perovskite contribution, which would indicate for example the presence of other Fe-bearing phases. This agrees with results from XRD, indicating that the minor parasitic spinel phase is poor in Fe, being close to the Co 3 O 4 stoichiometry.…”

Perovskites as Substitutes of Noble Metals for Heterogeneous Catalysis: Dream or Reality

“…The LaFeO 3 , LaCrO 3 , and LaMnO 3 perovskites were not structurally modified during autothermal reforming of isooctane, but these oxides were significantly less active than LaNiO 3 and LaCoO 3 . Further modification of the LaFeO 3 perovskite with Pd at the B site improved the catalytic performance but increases the problem of the higher cost of the material thus prepared . Addition of cerium in the A site of LaFeO 3 significantly increased the resistance to carbon deposition.…”
