Ammonia is added to solutions of cobalt, nickel, and copper 2+ cations. First formation of the hydroxide precipitate is seen, then of the ammonia complex. Pour 0.1M solutions of Cu2+, Co2+, and Ni2+ ...

However, its high cost has prevented its widespread adoption in large-scale ammonia synthesis. While cobalt (Co) has been considered as a more cost-effective alternative, achieving the same ...

Researchers in South Korea have developed a cobalt-iron (CoFe)-based non-noble metal ammonia decomposition catalyst, ...
