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.
