(Invited) Progress in Catalysts for Green Ammonia Synthesis

Research on catalysts for NH 3 synthesis at mild conditions has been much accelerated in that last decade as evidenced by rapidly increasing publication number of the papers[1]. In this talk I summarize the features of the various activation methods reported so far, looking chronologically back at progress in heterogeneous catalysts since the use of iron oxide for the Haber–Bosch process, introduce progress in new catalysts (Fig.1) and finally the current technical challenges to be overcome are presented.
