Abstract
AbstractDry reforming of CH4/CO2provides a promising and economically feasible route for the large‐scale carbon fixation; however, the coking and sintering of catalysts remain a fundamental challenge. Here we stabilize single‐crystalline Ni nanoparticles at the surface of porous single‐crystalline MgO monoliths and show the quantitative production of syngas from dry reforming of CH4/CO2. We show the complete conversion of CH4/CO2even only at 700 °C with excellent performance durability after a continuous operation of 500 hours. The well‐defined and catalytically active Ni‐MgO interfaces facilitate the reforming reaction and enhance the coking resistance. Our findings would enable an industrially and economically viable path for carbon reclamation, and the “Nanocrystal On Porous Single‐crystalline Monoliths” technique could lead to stable catalyst designs for many challenging reactions.
