High CO₂ Selectivity in Methanol Steam Reforming through ZnPd/ZnO Teamwork^†

Abstract

Together we are strong: Immediately after high-temperature reduction, ZnPd/ZnO catalysts are not notably CO₂ selective in the methanol steam reforming process. Under methanol steam reforming conditions, high CO₂ selectivity can only be achieved by the rather slow formation of ZnO patches on the surface of intermetallic ZnPd nanoparticles to create a highly synergistic interface.
