On the mechanism of photodriven hydrogenations of N2 and other substrates by Hantzsch ester: Buffer is key to reactive H-atom donors

Proceedings of the National Academy of Sciences, Volume 122, Issue 26, July 2025. <br/>SignificanceSolar-driven ammonia synthesis is an interesting approach to consider for fertilizer production and zero-carbon fuels. However, photocatalytic nitrogen fixation by well-defined synthetic catalysts was first demonstrated only very recently. Our …
