Photoassisted catalytic oxidation of carbon monoxide at room temperature
The thermal and photoassisted catalytic oxidation
of CO at metal oxide supported
| dc.abstract.en | The thermal and photoassisted catalytic oxidation of CO at metal oxide supported $RuO_{2}\cdot \chi H_{2}O$ was studied at room temperature. Contrary to neat $RuO_{2}\cdot \chi H_{2}O$ the support- ed catalysts suffer from fast deactivation attributed to strong adsorption of the reaction product carbon dioxide. The latter can be efficiently removed from the catalyst surface at ele- vated temperatures. In some cases, i.e. for catalysts supported with selected n-type semiconductors ($TiO_{2}$, $SnO_{2}$, $WO_{3}$), efficient $CO_{2}$ desorption and good, constant catalytic activity was observed upon visible light irradiation. Under such conditions the CO to $CO_{2}$ conversion observed for $RuO_{2}\cdot \chi H_{2}O/TiO_{2}$ was nearly as good and stable as for the unsupported catalyst. It is suggested that light absorption promotes carbon dioxide desorption through positive charging of the catalyst surface | pl |
