Methane conversion to hydrogen and nanotubes on Pt/Ni catalysts supported over spinel MgAl2O4

Methane decomposition is an endothermic process. Therefore a high temperature increases the methane conversion and improves the carbon accumulation. Nevertheless at high temperature conditions a faster deactivation of catalyst is generally observed. To keep the stability of the catalyst, lower reaction temperatures can be used as well as methane dilution but the catalytic activity is lowered. The aim of the present work consists in the study of the catalytic properties of Ni–Pt supported over MgAl2O4 for the selective conversion of methane into hydrogen and carbon nanotubes.
