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.
