Methane decomposition over metal oxides-supported nickel (Ni/MOX) catalyst was studied to produce green hydrogen without emission of carbon oxides. The Ni/TiO2 catalyst showed the highest activity for methane decomposition among Ni/MOX catalysts and this activity was higher than that of Ni/HZSM-5 catalyst. The catalyst life of Ni/TiO2 was longer than that of Ni/HZSM-5. Furthermore, catalytic life of Ni/TiO2 for methane decomposition were improved by Pd addition. Improved catalytic life of Ni/TiO2 by Pd addition were caused by formation of Ni-Pd alloy particle.
