Abstract
This work has shown that CO 2 molecules can interact at b.t. with high surface α-Fe 2O 3 obtained by thermal decomposition of goethite giving: a) physisorption, possibly via charge transfer mechanism between the carbon atom and the oxygen of a surface hydroxyl; b) formation of both monodentate and bidentate carbonate ions which can be easily decomposed by degassing even at b.t.. More severe conditions of contact allow the progressive formation of Fe 2O 2CO 3 layers thermally stable up to 400°C which can be identified through their characteristic IR absorptions.
