Highly Active Silica-supported Rhodium Phosphide Hydrodesulfurization Catalyst Prepared by Sequential Impregnation to Control the Rhodium and Phosphorus State

The effects of the preparation method on Rh and P species in P-added Rh catalysts, as well as hydrodesulfurization (HDS) activities, were investigated. Ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed reduction, X-ray diffraction (XRD), and CO adsorption analyses were use...
