Active Site Dependent Reaction Mechanism over Ru/CeO2 Catalyst toward CO2 Methanation
TL;DR: The catalytic activity evaluation and the oscillating reaction over Ru/CeO2 catalyst further prove that the oxygen vacancy catalyzes the rate-determining step with a much lower activation temperature compared with Ru surface in Ru/α-Al2O3 (125 vs 250 °C).
