摘要
To gain deep insight into the Morphological effect of NixMg1 (-) O-x catalysts on the reaction of CO2 reforming with methane, we designed and fabricated three different spatial structural NixMg1 (-) O-x catalysts. These NixMg1 (-) O-x catalysts with specific models such as rod, sheet and sphere, exhibited various activity and stability in CO2 reforming reaction. Herein NixMg1 (-) O-x nanorods displayed higher catalytic activity, in which methane conversion was up to 72% and CO2 conversion was 64% at 670 degrees C with a space velocity of 79,200 mL/(g(cat) h), compared with nanosheet and nanosphere counterparts. Furthermore, both catalysts of NixMg1 (-) O-x nanorod and nanosheet showed a high resistance toward coke deposition and sintering of active sites in the process of CO2 reforming of methane.
