Impact of A-Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL-DRM).
La1-xSrxFeO3 (0 ≤ x ≤ 1) perovskite oxygen carriers (OCs) were evaluated for dry reforming of methane (DRM) at 900°C under co-feed and chemical-looping (CL-DRM) configurations. Sr substitution decreased CH4/CO2 conversions in co-feed DRM, indicating suppressed intrinsic catalytic activity. In contrast, CL-DRM enhanced...
