| Abstract: | The catalytic activity and surface active oxygen species for CO oxidation on the complex oxides catalysts of La_(1-x)Sr_xCo_(1-x)B_xO_3(B=Fe,Ni,Cr) were investigated with micro reactor and TPD methods. According to the relation of activity and the amount of surface oxygen species, the active oxygen species for CO oxidation on this kind of catalyst were discussed. |
