摘要

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