TiO2 nanotubes supported NiW hydrodesulphurization catalysts: Characterization and activity

▸ NiW catalysts supported on TiO2 nanotubes, titania and alumina. ▸ The best results are obtained with NiW/TiO2 nanotubes in hydrodesulfurization (HDS) of thiophene. ▸ Active phase is Ni-WOxSy. ▸ Electronic promotion of W by Ti.
