Chemical looping {is an|is definitely an} emerging {technology|technologies} to {produce|create|generate|make} {high|higher} purity hydrogen from fossil fuels or biomass {with the|using the|with all the|together with the} simultaneous capture {of the|from the|in the|on the|with the|of your} CO2 {produced|created|made|developed} {at the|in the} distributed scale. This {process|procedure|method|approach|course of action} {requires|demands|needs|calls for} the availability of {stable|steady} Fe2O3-based oxygen carriers. Fe2O3-Al2O3 {based|primarily based} oxygen carriers exhibit a decay {in the|within the|inside the} H2 yield with cycle {number|quantity} {due to|because of|as a result of|on account of|resulting from|as a consequence of} the formation of FeAl2O4 that {cannot|can’t|can not} be re-oxidized. {In this|Within this} study, the addition of sodium ({via|by way of|through|by means of} a sodium salt) {in the|within the|inside the} synthesis of Fe2O3-Al2O3 oxygen carriers was assessed as a {means|indicates|implies|signifies|suggests} to counteract the cyclic deactivation {of the|from the|in the|on the|with the|of your} oxygen carrier. Detailed insight {into the|in to the} oxygen carrier’s structure was gained by combined X-ray powder diffraction (XRD), X-ray absorption spectroscopy (XAS) {at the|in the} Al, Na and Fe K-edges and scanning transmission electron microscopy/energy-dispersive X-ray spectroscopy (STEM/EDX) analyses. The addition of sodium prevented the formation of FeAl2O4 and stabilized the oxygen carrier {via|by way of|through|by means of} the formation of a layered structure, Na-β-Al2O3 phase.
