Results suggest there are two modes of deactivation during steam reforming of ethanol and E85 over Rh: reversible, and irreversible. Regeneration of a deactivated catalyst can only partially recover the initial activity due to the long-term deactivation. DFT shows the oxidation state of catalytic Rh nanoparticles changes dynamically under reaction conditions.
