Reduction of carbon dioxide during the synthesis of metal nano-particles in water

An effort was made to synthesize “carbon-free” metal (Fe 0, Co 0, Ni 0) nano-particles via the reduction of their salts with BH 4 − in aqueous solutions. Surprisingly it was found that when the synthesis is carried out in the presence of CO 2, e.g., in aerated solutions, the CO 2 is catalytically re...

Summary:An effort was made to synthesize “carbon-free” metal (Fe 0, Co 0, Ni 0) nano-particles via the reduction of their salts with BH 4 − in aqueous solutions. Surprisingly it was found that when the synthesis is carried out in the presence of CO 2, e.g., in aerated solutions, the CO 2 is catalytically reduced by BH 4 − on the surface of the metal particles. Carbon-free metals can be prepared by reduction under an inert atmosphere. Thus metal surfaces might have acted as catalysts for CO 2 fixation, probably via the initial formation of carbon clusters, in the reductive atmosphere in the prebiotic era.
