Nano size nickel oxide prepared by sol-gel method has better ethane oxidative dehydrogenation activity at lower temperature than by other methods. The diameter of particles calcinated at 380℃ is about 8 nm. Compared with large size nickel oxide catalyst, the reaction temperature over nano NiO was lowered about 125℃ when the same ethylene yield was obtained. The nickel oxide catalysts calcinated at different temperatures were characterized by BET, TPR, TPD, XPS, etc. And the particles size and its relationship with activation of oxygen and reaction activity were investigated.

Key words: oxidative dehydrogenation of ethane, nano, nickel oxide, sol-gel
