本文探讨了焙烧温度对催化剂结构及氨氧化活性的影响。得出:La_(0.9)Sr_(0.1)NiO_(3-λ)在1223K后分解,生成具有K_2NiF_4结构的La_2NiO_4相,NiO相和LaNiO_3相。催化活性相主要是具有钙钛矿结构的组分。最佳活性相在1273K形成。
In this paper, the effect of calcination temperature on the structure of catalyst and ammonia oxidation activity was discussed. The results show that La_ (0.9) Sr_ (0.1) NiO_ (3-λ) decomposes at 1223K to form La_2NiO_4 phase, NiO phase and LaNiO_3 phase with K_2NiF_4 structure. The catalytically active phase is mainly a component having a perovskite structure. The best active phase is formed at 1273K.
