摘要
NiO-MgO nanoparticles were encapsulated into the inner matrices of silica to form the core-shell structure. Such catalyst (NiO-MgO@SiO2) exhibited highly efficient activity for CO2 reforming of methane, in which above 80% methane conversion and about 70% CO2 conversion can be achieved at a low bed temperature (670 degrees C) with a high space velocity of 79200 mL g(-1) h(-1). Furthermore, such confined structure indeed ensures higher resistance toward the catalyst carbon deposition and the sintering of active sites for long-term performance, when compared to the conventional NiO-MgO/SiO2 catalyst.
