Efficient C-N coupling in the direct synthesis of urea from CO₂ and N₂ by amorphous Sb_xBi_1-xO_y clusters.

ABSTRACT: Although direct generation of high-value complex molecules and feedstock by coupling of ubiquitous small molecules such as CO₂ and N₂ holds great appeal as a potential alternative to current fossil-fuel technologies, suitable scalable and efficient catalysts to this end are not currently available as yet to be designed and developed. To this end, here we prepare and characterize Sb_xBi_1-xO_y clusters for direct urea synthesis from CO₂ and N₂ via C-N coupling. The introduction of Sb in the amorphous BiO_x clusters changes the adsorption geometry of CO₂ on the catalyst from O-connected to C-connected, creating the possibility for the formation of complex products such as urea.
