Abstract

Abstract:

Carbon-protected metallic nanoparticles（nickel and cobalt）composites were prepared by the pyrolysis of the mixture of soluble starch and metallic acetate in N₂ flow via an easy green synthetic route.The obtained samples were highly stable in air.Reducing agent was not used in the experiments.The as-synthesized samples were characterized by XRD，TEM，and N₂ adsorption-desorption analysis.The results of N₂ adsorption-desorption analysis indicated that the obtained samples possessed mesoporous structures and high BET surface areas.
