A novel route for synthesis of NiCoP/SiO2 hydrodesulfurization catalysts with active S species. (13th February 2018) - Song, Limin
Abstract : We report a new route for synthesis of NiCoP/SiO2 with active S species using NiS and CoS as precursors. The as‐prepared catalysts were characterized using X‐ray powder diffraction, N2 ‐adsorption specific surface area measurements, inductively coupled plasma atomic emission spectroscopy, transmission electron microscopy, and X‐ray photoelectron spectroscopy (XPS). The catalyst was highly active during the dibenzothiophene hydrodesulfurization (HDS) of NiCoP/SiO2 . The XPS spectra of the as‐obtained samples show that the surface of NiCoP contains a small amount of S species, which may be responsible for the higher HDS activity. Abstract : The NiCoP/SiO2 catalyst with higher HDS ability based on metal sulfides was successfully prepared. The paper provides a new route for synthesis of bimetal phosphides with high HDS ability.
