Abstract: In this work, experiments were performed to investigate the activity and regeneration ability of iron-based oxygen carrier with high index facet (104) during chemical looping combustion (CLC), suggesting that morphological control of the oxygen carrier is very rewarding. Fe 2 O 3 (104) supported on Al 2 O 3 was synthesized by a morphology controlled method to undertake maize stalk CLC experiments. Compared with the referenced Fe 2 O 3 /Al 2 O 3 prepared by the impregnation method, Fe 2 O 3 (104)/Al 2 O 3 presents better reactivity, showing higher fuel conversion rate and CO 2 concentration in gaseous products. Further, structural characterizations, including X-ray diffraction (XRD), scanning electron microscopy (SEM) (LEO-1450) and Brunauer-Emmett-Teller (BET) analysis, and multi-cycles CLC reactions were performed to verify the good regeneration and stability of the Fe 2 O 3 (104)/Al 2 O 3 . The findings indicate that the Fe 2 O 3 (104)/Al 2 O 3 is efficient when used for CLC of maize stalk.
