Nickel Ferrites Nanopowders as Catalysts for Hydrogen Production through NaBH4 Hydrolysis

Abstract

the two series of ferrites were synthesized. The first series was obtained by the traditional method of coprecipitation. The second series was synthesized by the new improved method which was named the coprecipitation with overheating. FTIR spectra had shown the tetrahedral and octahedral metals ions sites, and the XRD pattern confirmed the formation of cube structure with the stable lattice constant of ferrites in obtained nanopowders. The high catalytic activity of all synthesized nanoferrite catalysts in the sodium borohydride hydrolysis reaction was proved. But Nickel ferrites synthesized by a new method of coprecipitation with overheating showed significantly higher catalytic activity in the studied process of hydrogen production. The possibility of nickel ferrite nanopowders using for hydrogen production by hydrolysis of sodium borohydride has been shown and confirmed.
