The Ni/SiO2 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 similar to 10 nm within the pores of SiO2. The Ni particles in pores of mesoporous silica were not only resistant towards sintering but also coke formation during the reaction. In contrast, bare NiO nanoparticles were easily aggregated into larger particles and coke could form under the same reaction conditions, and therefore, much lower reactivity for CRM was found using bare NiO catalysts. It is suggested that Ni particles with very low loading on mesoporous SiO2 could be promising candidate as catalysts of CRM reaction. (C) 2013 Elsevier Ltd. All rights reserved.
