摘要
The surface active oxygen species of CO oxidation reaction on La 0.5 Sr 0.5 Ni 1 y Cu yO 3 catalyst were investigated using TGA , XPS and the transient response method. The results obtained from XPS show that there are two kinds of oxygen species on the catalyst, that is the surface absorbed oxygen species and the surface lattice oxygen species. In addition, the results of other experiments indicate that the surface absorbed oxygen species are the active species for CO catalytic oxidation.
