摘要：
The adsorption of O-2 and the CO oxidation reaction has been studied, by TDS and surface titrations, on a TiO2 nanotubes (TiNTs) array which consist of a 80/20% mixture of the anatase/rutile polymorph. Molecular O-2 adsorption, influenced by defects, as well as CO2 formation at low temperatures (similar to 100 K) were observed.
