【Abstract】 Fe/N and Fe/N/C ultrafine particles (UFP) were synthesized by laser induced vapor phase reaction method, using Fe(CO)5/NH3/SF6 and Fe(CO)5/NH3/C2H4 system. Examinations of TEM, IR, XRD and electron diffraction patterns were used to describe the characterishcs of the samples.Fe/N and Fe/N/C (UFP) have average diameters of 7.0 nm.更多还原
