Description
Lara K. Ribeiro and colleagues report, in 2026, a light-driven route to ammonia that improves when a porous polymer coats the catalyst. Ammonia underpins fertiliser production, but the industrial process uses fossil hydrogen and much energy. A catalyst made from nickel, molybdenum and oxygen can drive the reaction with light in water.
Under blue light at neutral pH, the earth-abundant catalyst produced ammonia from nitrogen, confirmed by colour testing and isotope experiments. Heating the catalyst reduced its water content and suppressed activity. Adding methanol helped, and coating the surface with a rigid microporous polyamine more than doubled the production rate. The authors propose that the polymer stores protons locally and returns them where ammonia forms.
