abstract = {We report on the one-pot synthesis of inexpensive and
abundant CeO2 and 1.5, 4.5, and 9 $mol\%$ Fe-doped ceria
(Ce1−xFexO2−δ) systems and their catalytic activity for
tandem CO2 hydrogenation. XAFS and XRD demonstrate that
oxygen vacancies are generated via two mechanisms: firstly,
by the substitution of Ce4+ by Fe3+ in the lattice and the
subsequent loss of oxygen anions. Secondly, by the partial
reduction of Ce4+ to Ce3+, which is enhanced by the presence
of Fe. All the samples tested show high activity for CO2
hydrogenation and the production of CO, CH4, and light
(C2–C4) alkanes and alkenes, with the 9 $mol\%$ Fe-doped
CeO2 showing the best performance in terms of CO2 reaction
rate and product selectivity. During reaction, Fe
exsolves/seggregates from the ceria, resulting in particles
decorating the surface of the catalyst and increasing the
reaction rates of CO2. This system is composed of two
functionalities, the oxygen vacancy and the Fe, whose close
vicinity results in a high selectivity toward CO and CH4
detrimental to the more valuable hydrocarbons. A rather
complex interplay between the two functionalities, their
interface, and the particle size of the catalysts exists for
this tandem reaction network on this catalytic system and
deserves further studies.},
