Supported nickel catalysts have been extensively applied in the industrial process for methane conversion (including steam reforming of methane, dry reforming of methane, partial oxidation of methane and methane decomposition). Compared with the supported noble metal catalysts, the nickel based catalyst is much cheaper and has high activity. However, there still exist many difficulties in the size, structure and performance control of the nickel based catalysts. Especially, the Ni catalyst faces serious carbon deposition problem, which leads to a deactivation of the catalyst for the above mentioned reactions. In this presentation, the size and structure control of the nickel based catalysts will be discussed. It has been found that the catalyst with small catalyst size (less than 10 nm), rich Ni(111) contents and enhanced metal-support interaction will have an improved catalytic properties and an enhanced stability. The catalyst preparation method will be found to play extremely important role in the catalytic performance.
