To gain deep insight into the Morphological effect of Ni_xMg_(1-x)O catalysts on the reaction of CO_2 reforming with methane, we designed and fabricated three different spatial structural Ni_xMg_(1-x)O catalysts.These Ni_xMg_(1-x)O catalysts with specific models such as rod, sheet and sphere, exhibited various activity and stability in CO_2 reforming reaction. Herein Ni_xMg_(1-x)O nanorods displayed higher catalytic activity, in which methane conversion was up to 72% and CO_2 conversion was 64% at 670°C with a space velocity of 79,200 mL/(gcath), compared with nanosheet and nanosphere counterparts. Furthermore, both catalysts of Ni_xMg_(1-x)O nanorod and nanosheet showed a high resistance toward coke deposition and sintering of active sites in the process of CO_2 reforming of methane.
