Novel Yb2O3-CuO catalysts with C-type cubic structure were synthesized for direct nitrous oxide (N2O) decomposition. By introducing Cu[Formula: see text] ions into Yb2O3 lattice, 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 (Yb[Formula: see text]Cu[Formula: see text]O[Formula: see text] catalyst, and the complete N2O decomposition was achieved at the temperature as low as 400[Formula: see text]C. In addition, the catalyst showed high durability for co-existing of oxygen gas and water vapor.

C型立方结构的Yb2O3-CuO催化剂上直接分解N2O

小说Yb2○3-合成了具有C型立方结构的CuO催化剂用于直接一氧化二氮（N2O) 分解。通过将 Cu[公式：见正文] 离子引入 Yb2○3晶格中，由于氧化还原性质的改善和氧化物离子空位的产生，催化活性的提高被认为是公认的。在所制备的催化剂中，(Yb[分子式：见正文]Cu[分子式：见正文]O[分子式：见正文]催化剂的活性最高，而完整的N2在低至400[公式：见正文]C的温度下实现O分解。此外，该催化剂对氧气和水蒸气的共存表现出高耐久性。
