Team Ammine

Ammonia is a carbon-free fuel produced on a scale of over 150 M tons / year.  We examine the fundamental chemistry of N-H and N-N bond cleavage and formation that guides the development of molecular electrocatalysts based on iron and copper to cleanly generate energy from NH3 and ultimately, to sustainably produce NH3 from N2.

Ferrocenium cleanly converts ammonia to dinitrogen, enabling ferrocene to serve as an electrocatalyst for ammonia oxidization

Tunable H-bonding at Cu-OH functionalities - next target: N2H2
