CO2 reforming of CH4 catalyzed by porous SiO2 and TiO2/SiO2-supported Ni was studied. Ni on the porous substrates was deposited using atomic layer deposition method, and after the catalytic reactions, Ni nanoparticles confined within the pores of the substrates were found. Both catalysts showed comparable catalytic activity and stability. The bare SiO2-supported catalyst showed very stable reactivity...
Mesoporous SiO 2 -supported Ni catalyst was fabricated by atomic layer deposition (ALD), and the catalytic activity and stability were investigated in carbon dioxide reforming of methane (CRM) reaction at 800°C. The Ni/SiO 2 catalysts showed high initial activity and catalytic stability in the CRM reaction as a result of confinement of Ni particles with a mean size of ∼10nm within...
