Self-regeneration of ferrites incorporated into matched matrices for thermochemical CO2 splitting

A completely different and convenient approach to the anti-sintering of ferrite materials for two-step thermochemical CO2 splitting is reported. Incorporated into matched matrices, ferrite particles can be dissolved and regenerated alternatively during the thermal cycling. With this approach, continuous sintering of the ferrite particles is avoided and high reactivity is retained, resulting in much better performance than conventional materials using thermostable supports to disperse ferrite particles.
