英文摘要 | Ni–MgO nanoparticles (NPs) encapsulated by porous silica shell for CO2 methanation were synthesized. The effects of Ni/Mg ratios in core–shell structured catalysts on CO2 conversion and CH4 selectivity were examined. Results showed that the NiO–MgO@SiO2 catalyst with a Ni/Mg ratio of 4/1 exhibited the highest catalytic activity (87% conversion for CO2 and 99% selectivity for CH4) and catalytic stability for the whole 100 h time on stream at low temperature (300 °C). It was found that the high catalytic activity and stability of this catalyst could be attributed to the isolated highly dispersed Ni NPs, which were obtained through the reduction of NiO–MgO solid solution protected by the silica shell. |
