The Chirik Lab reports room-temperature, photocatalytic ammonia synthesis from a N2-derived terminal molybdenum nitride, using photodriven, proton-coupled electron transfer that allows for H2 as the terminal reductant. This has not been accomplished before.

Building on a 2021 Nature Chemistry proof-of-concept paper in which the Chirik Lab reported that the irradiation of iridium hydride complexes with visible light enabled formation of weak X-H bonds, lead author Sangmin Kim took the strategy to the next level, synthesizing ammonia from the catalytic hydrogenation of the N2-derived nitride for the first time by using a molybdenum nitride compound …
