Catalytic activity of Co/SiO2 and Co/TiO2 nanosized systems in the oxidation of carbon monoxide

The effects of the preparation procedure, active component concentration, and conditions of formation of nanosized cobalt-containing systems based on TiO 2 and SiO 2 mesoporous powders on their catalytic activity in the oxidation of carbon monoxide were studied. The active phase in the systems was c...

Summary:The effects of the preparation procedure, active component concentration, and conditions of formation of nanosized cobalt-containing systems based on TiO 2 and SiO 2 mesoporous powders on their catalytic activity in the oxidation of carbon monoxide were studied. The active phase in the systems was cobalt spinel CoCo 2 O 4 found in all samples. High catalytic activity was found in the samples characterized by relatively high contents of surface active centers (cobalt cations with octahedral surroundings).
