The use of strontium ferrite in chemical looping systems ...

2018-8-1  This work reports a detailed chemical looping investigation of strontium ferrite (SrFeO 3−δ), a material with the perovskite structure type able to donate oxygen and stay in a nonstoichiometric form over a broad range of oxygen partial pressures, starting at temperatures as low as 250°C (reduction in CO, measured in TGA).SrFeO 3−δ is an economically attractive, simple, but remarkably ...
