合成了新型的c型立方结构Yb2O3-CuO催化剂,用于氧化亚氮的直接分解。通过在yb2o3晶格中引入Cuions,由于氧化还原性能的改善和氧化离子空位的产生,使得yb2o3的催化活性得到了增强。在所制备的催化剂中,(ybcuo)催化剂的活性最高,在低至400℃的温度下可实现N2O的完全分解。此外,该催化剂在氧气和水蒸气共存的条件下表现出较高的耐久性。
Novel Yb2O3-CuO catalysts with C-type cubic structure were synthesized for direct nitrous oxide (N2O) decomposition. By introducing Cuions into Yb2O3lattice, the enhancement in the catalytic activity was recognized owing to the improvement of redox properties and the generation of oxide ion vacancies. Among the catalysts prepared, the highest activity was obtained for the (YbCuOcatalyst, and the complete N2O decomposition was achieved at the temperature as low as 400C. In addition, the catalyst showed high durability for co-existing of oxygen gas and water vapor.
