► A comparison study of NiMo/silica and NiMo/titania-silica catalysts was undertaken. ► Different types of silica (MCM-41, SBA-15, amorphous silica) were modified with TiO2. ► Titania addition to the silica supports increased the dispersion of the NiMo species. ► Catalytic activity was tested in HDS...
