| Abstract: | The morphologies,chemical composition and crystal structure of the nanorod arrays on the sulfurated hydrorefining catalyst surface were studied by scanning electron microscopy(SEM),high resolution transmission electron microscopy(HRTEM),selected area electron diffraction(SAED)and X-ray energy disperse spectroscopy(EDS).The nanorod arrays were observed by SEM,which widely distributed on the catalyst surface.The nanorod arrays grew outward from the surface and assumed their regular shapes with lengths of 500-... |
