- •
CeO2/3DOM LaFeO3 oxygen carrier shows high activity and stability for the coproduction of syngas and hydrogen by chemical-looping reforming of methane (CLRM).
- •
The presence of CeO2 nano particles (2–3 nm) on 3DOM LaFeO3 induce greater formation of oxygen vacancies, which strongly improves the reducibility, oxygen mobility and the resistance towards carbon formation.
- •
The design of efficient oxygen carriers for CLRM must consider the balance among the concentration of active sites for recants activation, the oxygen diffusivity and the available OSC.
