英文摘要A modified confined catalyst with CeO2 on the interior and CuO on the exterior surface of TiO2 nanotubes (Ce-in-TNT-Cu-out) was prepared and investigated for the combustion of butane catalytically. Compared with the Ce-in-TNT and TNT-Cu-out, the Ce-in-TNT-Cu-out presents a higher activity for butane oxidation, with a conversion of 10% at 200 degrees C and a conversion of 90% at 300 degrees C. XPS analysis indicates that more Ce(IV) and Cu(I) components exist in the Ce-in-TNT-Cu-out catalyst. It is proposed that electron transfer ability between encapsulated CeO2 and loaded CuO is significantly enhanced by the confinement effect of the TiO2 nanotubes, facilitating the formation and migration of active oxygen species in the catalyst. This result shows that modulating the electronic property of the active component can further improve the catalytic combustion performance of the confined catalysts.
