Large scale carbon fixation requires high volume chemicals production from CO<sub>2</sub>. Dry reforming of methane could provide an economically feasible route if coke and sintering resistant catalysts were developed. We developed a molybdenum doped nickel nanocatalyst that is stabilized at the edges of a single crystalline MgO support (NiMoCat) that shows quantitative production of synthesis gas from dry reforming of methane. The catalyst runs over 600 hours of continuous operation with no detectable coking. Synchrotron studies also show no sintering and reveal that 2.9 nm as synthesized particles move to combine into stable 17 nm grains at the edges of MgO crystals above the Tammann temperature. Our findings enable an industrially and economically viable path for carbon reclamation.
