【Abstract】 Fe-Ni nano-alloy was synthesized by chemical reduction,and the result of transmission electron microscopy（TEM） shows that the diameter of particles is very small.This nanosized alloy has high surface energy after reduction in H₂ at 400℃ and test can react with organic chloride.The result of element analysis indicates that the reaction products are Cl₂,FeCl₂ and NiCl₂.X-ray diffraction（XRD） and X-ray Photoelectron Spectroscopy（XPS） analysis show that Fe_xC is produced after baking in N₂ at 600 ℃.更多还原
