a) Hydrogenation and cleavage of N2 to NH3 with a Zr complex. b) N2 reduction and hydrogenation to NH3 with Fe complexes. c) N2 cleavage and hydrogenation to NH3 with a U complex (this work).
The electrochemical reduction of N2 to NH3 offers a means for storing solar energy and distributed production of fertilizers. The picture shows continuous capture of N2 from the air and its conversion ...
