| Ordered mesoporous materials, which have been attracted much attention in various kinds of applications, exhibit large surface areas, high porosities, controllable and narrowly distributed pore sizes in nanoscale, and an ordered pore arrangement. In general, the synthesis of mesoporous materials usually involves the use of a soft template (surfactant) via self-assembly or a hard template (mesoporous silica) via nano-replication. The latter method is known to be excellent to produce various kinds of mesoporous materials constructed with transition metal oxide frameworks. In the present work, the preparation of highly ordered mesoporous nickel oxide (NiO) via the nano-replication method from mesoporous silica, KIT-6, is reported. Various kinds of preparation parameters such as the amount of nickel precursors, the annealing temperature and period, and the nature of precursors have been studied in order to optimize the synthesis of mesoporous NiO. The results indicate that the anions in the nickel precursors are the most important factor in the formation of mesoporous nickel oxide. |
