| Abstract: | Effects of typical modifiers (Al: textural, Co: alloying and K: electronic) have been studied on Fe/MgO catalysts. Addition of Al modified the structure of iron oxide phase; the Co additive was incorporated mainly in bimetallic Fe?Co particles, while the potassium promoter has not exerted observable structural change. The results of Mössbauer studies are correlated with data of catalytic measurements in CO+H2 reaction. |
