Unveiling the critical role of TiO₂-supported atomically dispersed Cu species for enhanced photofixation of N₂ to nitrate.

ABSTRACT: Nitrate products are widely used in manufacturing as crucial raw materials and fertilizers. The traditional nitrate synthesis process involves high energy consumption and emission, thereby opposing the goals of zero-carbon emission and green chemistry. Thus, a sustainable roadmap for nitrate synthesis that uses green energy input, clean N sources, and direct catalytic processes is urgently required (e.g., developing a novel photosynthesis system). Here, we synthesized TiO₂-supported atomically dispersed Cu species for N₂ photofixation to nitrate in a flow reactor. The optimized photocatalyst yielded a high nitrate photosynthesis rate of 0.93 μmol h^-1 and selectivity of ∼90%, which is superior to most of the values reported thus far. Further, experime
