Dry reforming of methane (DRM) is the most viable way to recycle massive amount of carbon dioxide into fuel as syngas. However, lack of unstable catalysts has been the major obstacle as unwanted coke or sintering deactivates catalyst. Here, we developed stable Ni-Mo catalyst supported on single crystalline MgO for DRM. Ni-Mo nanocrystals were synthesized in the presence of single crystalline MgO through polyol method. The catalyst showed no sign of coking or sintering even after 850 hours of test at 800 <sup>o</sup>C. In situ TEM showed that 3 nm Ni-Mo nanoparticles in as-synthesized catalyst migrated to the vertex and edge of single crystalline MgO while heated under reactive condition. We named this phenomenon “Nanocatalysts On Single Crystal Edge” (NOSCE) technique. NOSCE technique can offer industrial scale applications of transition metal catalysts and could be applied to other reforming reactions with different combinations.
