Catalytic decomposition of methane was investigated over nickel and cobalt based mono-and bimetallic catalysts for the production of hydrogen and filamentous carbon. Catalysts with different Ni to Co ratios supported on La2O3were prepared by co-precipitation method. The activity test and characterization results revealed that the catalyst containing 15wt% Ni and 10wt% Co over La2O3support presented relatively better catalytic performance among all the tested catalyst. The catalysts were characterized by BET, TGA and temperature programmed reduction (TPR).

In this paper the effect of changing different supports, calcination temperature and Ni loading on carbon dioxide reforming of methane using Ni-based catalyst are explored experimentally. The supports used are alumina (with different surface areas), silica, titania and zirconia. Calcination temperature is ranged from 773 to 1073 K, while nickel loading is ranged from 0 to 22% .The results showed that calcination at 873 K led to an acceptable catalyst activity. High surface area alumina proved to be the best support in terms of both activity and stability. 12% nickel loading proved to be satisfactory.
