摘要：
NiWO4 nanoparticles were prepared by a hydrothermal approach. The NiWO4 nanoparticles and their sulfided product were characterized by using different methods, such as X-ray powder diffraction, transmission electron microscopy and N2 adsorption. The hydrodesulfurization activity of NiWO4 nanoparticles was evaluated on micro device. The results showed that NiWO4 nanoparticles had an extremely high hydrodesulfurization activity for 4, 6-dimethyldibenzothiophene. The NiWO4 phase and nano size were the keys to the high hydrodesulfurization activity of NiWO4 nanoparticles.
