Abstract
•Influence of TiO2 structure on CuO/TiO2 catalysts.•These are a lot of Cu+ ions and oxygen vacancies that exist on CuO/TiO2 (rutile) catalyst.•CuO/TiO2 (rutile) catalyst is readily reduced.•CO species can adsorb to form Cu+ (CO)2 and O2 can adsorb to form O2−.
The present work tentatively investigated anatase- or rutile-supported copper oxide catalysts. 5% copper oxide can be well dispersed on anatase or rutile surfaces. The copper oxide dispersed on rutile surface exists in Cu2+ and Cu+ ions, which is more readily reduced, and show higher catalytic activity of CO oxidation. The mechanism of CO oxidation over rutile support is different from anatase support.
