Abstract
Doped CeO_2 with a low specific surface area is thermochemically cycled between MO_2 and MO_(2-δ) using H_2O and CO_2 as oxidants. The system rapidly and selectively produces syngas in the absence of a metal catalyst, and CH_4 in the presence of Ni. The Ni catalyst, which permits intermediate C to form on its surface, is proposed to shift the product from syngas to CH_4
