The high su- perficial energy of nano-alloy causes breakage of C-Cl bond in the presence of a little oxygen. XRD result shows the main phases of the alloy embedded with elemental carbon are Fe3C, Fe2C. The result of element analysis indi- cates that the reaction products are mainly FeCl2, NiCl2, Cl2.展开更多
