A series of Rh-promoted La0.75Sr0.25(Fe0.80Co0.20)(1-x)AlxO3-δ (x=0, 0.10, 0.25, 0.40, 0.60) samples were investigated as oxygen reservoirs for the conversion of CH4 to syngas at 873K and 1atm. Neutron powder diffraction studies revealed a decreasing rhombohedral distortion on increasing Al-content. XPS and TEM were employed to investigate surface chemistry and morphology of the Al=0.25 sample. The...
The cyclic reaction between CH 4 and O 2 over perovskite-type La 0.8 Sr 0.2 Fe 0.8 Co 0.2 O 3−δ , La 0.75 Sr 0.25 Fe 0.6 Co 0.15 Al 0.25 O 3−δ and La 0.8 Sr 0.2 Fe 0.8 Co 0.2 O 3−δ /γ-AlO(OH), impregnated with 0.5wt% Rh or Pt, was studied at...
