氨合成催化剂的进展

Recent progress in ammonia synthesis catalysts

Fe1-xO催化剂体系和钌催化剂的发现,标志着合成氨催化剂的研究取得了重大进展。Fe1-xO催化剂体系的发明,使氨合成催化剂的活性有了一个飞跃性的进步,为熔铁催化剂的发展注入了生机。钌催化剂的发明则有可能成为真正突破经历了近一个世纪的铁催化剂的使用历史。由于钌的稀有和昂贵,要在工业上广泛应用,还需要做大量的研究。

Invention of ruthenium and non-conventional Fe_(1-x)O-based ammonia synthesis catalysts represent a breakthrough in ammonia synthesis catalysts. Development of Fe_(1-x)O-based ammonia synthesis catalysts challenged the traditional theory that Fe_3O_4 was the most effective precursor for ammonia synthesis catalysts, and greatly enhanced their activity. Ru-based ammonia synthesis catalyst is promising as the substitute to the century-long iron-based catalysts. A lot of work have to be done in modification of ruthenium catalysts before the 'precious-metal' catalysts become commercially (feasible.)
