Abstract
The present invention describes a solid-solution synthesis method for producing porous Fe-containing active material (74) wherein Fe is interwoven with supporting oxide(s) by the following steps: mixing (64) Fe-containing specie (α) (60) and a supporting specie (β) (62) containing element of X, to provide a mixture (66), high-temperature treatment (68) to provide a Fe—X—O solid solution (70), and reducing (72) the solid solution to provide the Fe-containing active material wherein Fe is interwoven with X oxide(s) (74).
