Reaction characteristic of Fe–Ni nano-alloy with organic chloride

Fe–Ni nano-alloy which was prepared by chemical reduction with KBH4 as reductant and polyethylene glycol (PEG) as dispersant had high surface energy after being deoxidized in H2 atmosphere at 400 °C. It could cause breakage of C–Cl bond of organic chloride in the presence of a small amount of oxygen. The result of elemental analysis indicated that the reaction products were FeCl2, NiCl2 and Cl2, the production of Cl2 was because of the combination of Cl atom or Cl free radical that came from the breakage of C–Cl bond. High-performance liquid chromatography (HPLC) result showed that the existence of new organic compound such as biphenyl and so on. The results of X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) showed that carbon free radical or carbonaceous free radical enchased on the surface of nano-alloy and produced Fe3C, Fe2C after being baked in N2 atmosphere at 600 °C.
