摘要: Catalytic activities of five non-conducting and three superconducting cuprates were measured for the decomposition NO reduction by CO. The concentration reactants space velocities approximate conditions automotive catalysts. In contrast to earlier results, obtained at 20 30 times higher partial pressures 100 lower velocities, none catalysts, including perovskite-like cuprates, showed significant activity reaction temperatures up 700 °C. All catalysts fairly active NO. At above about 400 °C on YBa2Cu3O7-x Ba2CuO3.5-x , rates than CuO. lost in presence oxygen (oxidizing conditions).
