CO sub(2) Hydrogenation over Oxide-Supported PtCo Catalysts: The Role of the Oxide Support in Determining the Product Selectivity
By simply changing the oxide support, the selectivity of a metal-oxide catalysts can be tuned. For the CO sub(2) hydrogenation over PtCo bimetallic catalysts supported on different reducible oxides (CeO sub(2), ZrO sub(2), and TiO sub(2)), replacing a TiO sub(2) support by CeO sub(2) or ZrO sub(2) s...

| description | By simply changing the oxide support, the selectivity of a metal-oxide catalysts can be tuned. For the CO sub(2) hydrogenation over PtCo bimetallic catalysts supported on different reducible oxides (CeO sub(2), ZrO sub(2), and TiO sub(2)), replacing a TiO sub(2) support by CeO sub(2) or ZrO sub(2) selectively strengthens the binding of C,O-bound and O-bound species at the PtCo-oxide interface, leading to a different product selectivity. These results reveal mechanistic insights into how the catalytic performance of metal-oxide catalysts can be fine-tuned.Original Abstract: Die Selektivitaet von Metall-Oxid-Katalysatoren kann durch den Austausch des Oxidtraegers leicht veraendert werden. Fuer die CO sub(2)-Hydrierung mit PtCo-Katalysatoren auf verschiedenen reduzierbaren Oxidtraegern staerkt der Austausch eines TiO sub(2)-Traegers durch CeO sub(2) oder ZrO sub(2) die Bindung von C,O- und O-gebundenen Intermediaten an der PtCo-Oxid-Grenzflaeche, wodurch die Produktselektivitaet veraendert wird. |
