TiO_2 nanotubes(TiO_2-NTs) were synthesized by the hydrothermal method.Co and Mo active components were supported on a series of the as-prepared TiO_2-NTs samples which were calcined at different temperatures.The effects of support calcination temperature of CoMo/TiO_2- NTs catalysts on their catalytic performance were investigated for selective hydrodesulfurization(HDS).The samples were characterized by means of the scanning electron microscopy(SEM),the transmission electron microscopy(TEM),N_2 adsorption-desorption,X-ray diffraction (XRD),Raman spectroscopy and H_2 temperature-programmed reduction(H_2-TPR).The experimental results revealed that TiO_2-NTs support calcined under 500℃can maintain the nanotubular structure with higher surface area and pore volume.Meanwhile,the obtained supported CoMo/TiO_2-NTs catalysts exhibited weak metal-support interaction,more octahedral Mo~(6+) species and high catalytic performance in selective HDS. TiO 2 nanotubes (TiO 2 -NTs) were synthesized by the hydrothermal method. Co and Mo active components were supported on a series of the as-prepared TiO_2-NTs samples which were calcined at different temperatures. These effects of supporting calcination temperature of CoMo / TiO 2 - NTs catalysts on their catalytic performance were investigated for selective hydrodesulfurization (HDS). The samples were characterized by means of the scanning electron microscopy (SEM), the transmission electron microscopy (TEM), N2 adsorption-desorption, X-ray diffraction Raman spectroscopy and H 2 temperature-programmed reduction (H 2 -TPR). The experimental results revealed that TiO 2 -NTs supported calcined at 500 ℃ could maintain the nanotubular structure with higher surface area and pore volume. However, the obtained CoMo / TiO 2 -NTs catalysts exhibited weak metal-support interaction, more octahedral Mo ~ (6+) species and high catalytic performance in selective HDS.
