  "abstract": "La1‐xSxFeO₃ (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 CH₄ conversion by LaFeO₃ to ∼75%–79% but promoted carbon deposition and a deviation of the H₂/CO ratio from 2 (2.6). Sr‐containing compositions exhibited lower CH 4 conversion but improved carbon balance and syngas selectivity. La0.7Sr0.3FeO₃ provided the best compromise, achieving ∼40% CH₄ conversion, an ideal H₂/CO ratio of 2, and a carbon balance above 95%. Sr²⁺ substitution induces Fe⁴⁺/Fe³⁺ charge compensation and modifies the oxygen‐defect environment. The improved coke resistance is primarily associated with the suppression of nonselective CH₄ cracking rather than with enhanced oxygen mobility. These findings establish that selective and stable syngas production in CL‐DRM is governed not by maximizing oxygen reactivity, but by precisely balancing oxygen exchange kinetics with methane activation.",
