A Facile Synthesis Strategy of Ni@yolk-meso-SiO2 for Catalytic Dry Reforming of Methane Zi-Yian Lim, Xiaoxi Ma, Baiman Chen



This paper reports a synthesis strategy to develop Ni@yolk-meso-SiO2 by adopting the leaching and re-deposition of silica in mild alkaline solution with CTAB as stabilizer. It was compared to Ni@SiO2 core-shell catalyst and point out their difference in catalytic performance. The catalyst shows stable and near equilibrium conversion of methane and carbon dioxide for 50 hours. The increased in surface area and total pore volume contributed its high activity and stability.
