High temperature oxide superconducters Ba_(2-x)Sr_xYCu_3O_(7-a) (x=0, 0.25, 0.50, 0.75, 1.0, 1.25) was prepared using high purity BaCO_3, SrCO_3, Y_2O_2, CuO. The super-conducting transition temperature (T_c) of the samples was measured by the four-probe technique for resistivity and alternative current method for magnetic suscepti-bility. The properties of the superconductots were examined by using powder XRD method, EXAFS, laser Raman spectroscopy, TG and high vacuum mass spectroscopy TPD. The amount of substitution x is larger, the T_c is lower, the lattice parameters a, b, c and V are smaller and the occupation of oxygen is lower. The catalytic activity of these oxides for CO oxidation was also detected by continuous flow system at 1 atm. The easier released oxygen of these oxides O_I, the most active oxygen in the lattice, is the active center in catalytic oxidation by CO. The reaction mechnism is the same as that of Ba_2YCu_3O_(7-δ). Furthermore, there is a linear relationship between the catalytic activity and the amount of O_I.
