Recrystallization raises reactivation: Initial deactivation (blue frame) of NiCo/CeZr catalysts employed for methane dry reforming reactions can be correlated to oxidation of nanosized NiCo particles. With time on stream, sintering and growth (red frame) slowly leads to their reduction and reactivation. Reactivation is additionally promoted by parallel recrystallization of Ce0.8Zr0.2O2 support, which improves oxygen mobility and oxygen storage capacity. DR=Dry reforming.
