Tuning the Interaction between Ruthenium Single Atoms and the Second Coordination Sphere for Efficient Nitrogen Photofixation (Adv. Funct. Mater. 12/2022)

Nitrogen Photofixation In article number 2112452, Xusheng Zheng and co-workers present N2 photofixation to ammonia over a CoO-supported Ru single-atom catalyst. The Ru-Co coordination between Ru single atoms (yellow spheres) and Co atoms (blue spheres) serves as an additional electron transfer channel. This channel promotes more photogenerated electrons to accumulate at Ru atoms, thus increasing photoelectron density and N2 photofixation performance over Ru active sites.
