TL;DR: In this article, several ternary spinels were used for chemical looping CO2 splitting at moderate temperatures, and the results showed that the spinels achieved high CO 2 splitting rate and high CO production.

TL;DR: The sintering of oxygen carrier materials can be circumvented by operating chemical looping at relatively low temperatures (see as mentioned in this paper for a detailed discussion of the effects of looping on oxygen carrier material sinterment).

TL;DR: In this paper, the authors show that the oxygen releasing rate can be well controlled within a long reaction period by the specific spatial structure, demonstrating a new strategy to tune the oxygen diffusion in chemical looping process.
Abstract: Chemical looping redox cycle of oxygen storage materials offers a versatile platform to convert methane to value-added products in a clean and efficient manner. However, the highly dynamic nature of the oxygen diffusion process restrains the selective formation of the target products over a long reaction period. In this work, we show the oxygen storage materials-comprising of iron oxides and zirconium oxide support, with the nickel catalyst controllably deposited—that significantly enhanced the syngas selectivity. Mechanistic study indicated the oxygen releasing rate can be well controlled within a long reaction period by the specific spatial structure, demonstrating a new strategy to tune the oxygen diffusion in chemical looping process. Through the observed spatial effects, this work can be also extended to develop more oxygen storage materials for the other chemical looping applications, e.g. methane reforming, methane oxidative coupling, ethane oxidative dehydrogenation, etc.
