摘　　要：Poly(N-vinyl-2-pyrrolidone)(PVP)-stabilized ruthenium nanorods with high aspect ratio by refluxing ruthenium(Ⅲ) chloride in n-propanol have been successfully prepared by means of a facile and rapid microwave heating for the first time.The structure and morphology of the obtained products were characterized by transmission electron microscopy(TEM),select area electron diffraction(SAED),ultraviolet-visible spectrophotometry(UV-vis),X-ray photoelectron spectroscopy(XPS) and Fourier transform spectroscopy(FT-IR).XPS analysis reveals that the nanorods were in the metallic state.TEM images showed that ruthenium nanorods had an obvious one-dimensional structure with the aspect ratio ranged from 5 to 40 nm and length up to 600 nm.SAED patterns indicated that the nanorods were single-crystalline with a hexagonal structure.Poly(N-vinyl-2-pyrrolidone)(PVP)-stabilized ruthenium nanorods with high aspect ratio by refluxing ruthenium(Ⅲ) chloride in n-propanol have been successfully prepared by means of a facile and rapid microwave heating for the first time.The structure and morphology of the obtained products were characterized by transmission electron microscopy(TEM),select area electron diffraction(SAED),ultraviolet-visible spectrophotometry(UV-vis),X-ray photoelectron spectroscopy(XPS) and Fourier transform spectroscopy(FT-IR).XPS analysis reveals that the nanorods were in the metallic state.TEM images showed that ruthenium nanorods had an obvious one-dimensional structure with the aspect ratio ranged from 5 to 40 nm and length up to 600 nm.SAED patterns indicated that the nanorods were single-crystalline with a hexagonal structure.
