La0.6Sr0.4Co0.2Fe0.8O 3-? perovskite powder was prepared by a single-step process based on a microwave-assisted citrate gel route. The structure, morphology, as well as surface properties and thermal stability of the resulting material were deeply investigated by different techniques (XRD, SEM, XPS, BET and TGA). The powder resulted homogeneous with an excellent thermal stability. Preliminary catalytic tests revealed a promising activity in alcohol steam reforming. This simple, fast and general synthetic approach is expected to be valuable in order to open the path towards a scale up in the production of these materials.

Abstract
La0.6Sr0.4Co0.2Fe0.8O 3-? perovskite powder was prepared by a single-step process based on a microwave-assisted citrate gel route. The structure, morphology, as well as surface properties and thermal stability of the resulting material were deeply investigated by different techniques (XRD, SEM, XPS, BET and TGA). The powder resulted homogeneous with an excellent thermal stability. Preliminary catalytic tests revealed a promising activity in alcohol steam reforming. This simple, fast and general synthetic approach is expected to be valuable in order to open the path towards a scale up in the production of these materials.| File | Dimensione | Formato | |
