The activities of Ni catalysts with different supports in methane decomposition have been studied.The activity order of the catalysts is Ni/SiO₂ >Ni/MgO-Al₂O₃ >Ni/CaO-Al₂O₃ >Ni/α-Al₂O₃ and the interaction between Ni and the support is in the order of Ni/SiO₂ 2O₃ 2O₃ 2O₃.It is thus concluded that the weaker the interaction between Ni and support,the higher the activity of the catalyst.It was also found that the activity of the silica supported Ni-catalyst was increased with increase in its average pore radius and predominance pore radius.
