For a dry reforming of methane (DRM), Ni-based catalysts have a lot of problems due to their thermal instability by a sintering of supported Ni nanoparticles (NPs) to form less active larger agglomerates at a high temperature as well as significant coke formation compared to the novel metal-based catalysts. In order to suppress those limitations for a commercial application, the ordered mesoporous materials of SiO2 and Al2O3 were used to solve the deactivation of Ni nanoparticles, which were synthesized by a chemical reduction method by using nickel (II) acetylacetonate with borane tertbutylamine. The Ni nanoparticles were successfully confined in the ordered mesoporous structures, which suppressed the aggregations of the confined Ni nanoparticles thus showed a stable production of syngas at a high temperature without any significant aggregation and coke deposition. |
