Figure 3.
Simplified 8[e−/H+] kinetic scheme for nitrogen reduction. In the Lowe–Thorneley En notation, n = number of [e−/H+] added to FeMo-co; in parentheses, the stoichiometry of H/N bound to FeMo-co. The re/oa equilibrium is highlighted in red, and the intermediates in red boxes have been freeze trapped for spectroscopic study.
