Abstract

An effort was made to synthesize "carbon-free" metal (Fe 0, Co0, Ni0) nano-particles via the reduction of their salts with BH4- in aqueous solutions. Surprisingly it was found that when the synthesis is carried out in the presence of CO2, e.g., in aerated solutions, the CO2 is catalytically reduced by BH4- 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.
