Magnetically Propelled Microrobots toward Photosynthesis of Green Ammonia from Nitrates (Small 14/2025)

Ammonia Synthesis In article number 2407050, Martin Pumera and co-workers demonstrate magnetic ammonia-generation microrobots photosynthesizing ammonia from nitrates. Controlled by a rotating magnetic field, these microrobots can convert nitrate to value-added green ammonia using renewable light energy sources. The magnetic propulsion of the microrobots significantly improves mass transfer and enhances the efficiency of the photochemical synthesis of ammonia.
