Dry Reforming of Methane (DRM) is a process of primary interest in catalysis, in which two of the most abundant anthropogenic greenhouse gases – CO2 and CH4 – are converted into syngas (CO+H2) that can further be processed into fuels and valuable chemicals. Industrial DRM catalysts suffer from rapid deactivation due to coke formation, motivating the search for novel coke-resistant catalysts which could accelerate commercialization of DRM-based technologies. Mixed metal oxides with increased mobility and storage capacity of oxygen facilitate the removal of coke precursors from the catalytic surface. Moreover, dynamically created oxygen vacancies on their surfaces are capable of CO2 activation and its transformation into CO. In our previous reports , we demonstrated that concurrent CH4 activation can be achieved on the same materials by dispersing small clusters of transition metals (Pt, Ru, Ni, or Ni-Ru) on mixed (PrSmCeZr) metal oxide surfaces. Herein, transient Temporal Analysis of Products (TAP) experiments are used to gather compelling evidence of the Mars-van Krevelen-type (MvK) mechanisms that govern DRM reactions on these complex catalysts, specifically on Ni-Ru-Sm0.15Pr0.15Ce0.35Zr0.35O2
