| Abstract | Barium cerate (BaCeO3) and yttrium-doped barium cerate (BaCe0.9Y0.1O3-δ) were synthesized by the citric acid method and used as supports for Ru/BaCeO3 and Ru/BaCe0.9Y0.1O3-δ catalysts prepared by incipient wetness impregnation using Ru3(CO)12 as precursor. The supports and catalysts were characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Their catalytic properties for ammonia synthesis were evaluated in a fixed-bed reactor. The stability of BaCeO3 was superior to that of BaCe0.9Y0.1O3-δ, and the catalytic activity of Ru/BaCe0.9Y0.1O3-δ was higher than that of Ru/BaCeO3. The rate of ammonia synthesis over Ru/BaCe0.9Y0.1O3-δ was 432.5 ml/(g·h) at 3.0 MPa, 425 oC, and 15 000 h−1, which was 1.6 times higher than that of Ru/BaCeO3. The electronic interaction between Ce4+ and Ru nanoparticles was the key factor for the difference in catalytic activity and stability. |
