dc.abstract.en The thermal and photoassisted catalytic oxidation of CO at metal oxide supported RuO 2 x H 2 O was studied at room temperature. Contrary to neat RuO 2 x 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 ), effi- cient 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 x 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
