Niw Catalysts Supported on Titania Nanotubes for Hydrodesulfurization

NiW catalysts supported on titania nanotubes were prepared using different precursors, characterized and tested in HDS of dibenzothiophene and 4,6-dimethyldibenzothiophene. It was shown that all of them were more active than the reference NiW/γ-Al₂O₃ sample. The best results were obtained with the NiW-P/NT catalyst prepared using phosphotungstic acid as precursor.
