“…103 Similarly, calcium oxide (CaO) is an excellent support because it is low-cost 104,105 and has a high adsorption property toward CO 2 (∼786 g of CO 2 per kg of CaO (ref. 106 and 107)). The CaO support would make the catalyst size larger, but the conversion remains stable because CaO could eliminate the deposited carbon.…”

“…The basic principle of CLC is to decompose the traditional combustion method of direct contact between fuel and air into two gas–solid reactions with the help of oxygen carriers (OCs). The fuel and air need not be in contact, and the oxygen in the air will be transferred to the fuel by OCs. − Chemical looping of oxygen uncoupling (CLOU) is a variant of chemical looping that accelerates fuel conversion through the release of gaseous O 2 from OC itself, resulting in a higher fuel conversion rate. , As an important part of the CLOU, the performance of OCs affects the entire process. OCs should have the following characteristics: strong oxygen absorption, release ability, high activity, high mechanical strength, etc. − Copper-based OCs have attracted much attention because of the high reactivity and high oxygen loading rate. − …”

Chemical looping combustion technology has received attention as a novel combustion technology. In this paper, anhydrous citric acid was selected as the complexing agent and copper-based oxygen carriers (OCs) were prepared by the combustion synthesis method. The characteristics of NO x release during the combustion synthesis of copper-based OCs were investigated by citric acid addition. The NO release decreased significantly as the molar ratio of citric acid and Cu(NO 3 ) 2 •3H 2 O (R) increased. The peak NO concentration decreased from 100 to almost 0 ppm. The peak NO 2 concentration was maintained in the range 0−4 ppm. When R was less than 1.00, the products of copperbased OC precursor combustion were mainly NO, with very little generation of NO 2 . When R reached 1.25, only a very small amount of NO 2 was produced, and NO was negligible. The redox properties of the prepared copper-based OCs during 10 cycles were explored. The copper-based OCs all had stable redox properties in cycles. In each reduction, the peak CO 2 concentration was 3% and above. The CH 4 conversion rate and CO 2 yield were maintained at about 80% during the 10 cycles. The CO 2 selectivity was maintained at 95% and above. Among them, OC5 (R: 1.25) had the best redox capacity.

“…Traditional combustion was performed in the air atmosphere; it is not conducive to the separation of CO 2 ; normal catalytic combustion also has the same problem, while the combustion temperature in pure oxygen is higher; the equipment is easy to be damaged. However, chemical looping combustion (CLC) can realize the full transformation at mild conditions for CCUS. , A large quantity of CLC catalysts have been investigated, including various supports, active metals, and so forth, and the catalysis performance depends on the selection of the oxygen carrier to a great degree . An excellent oxygen carrier with favorable structure stability and higher oxygen-carrying capacity is extremely desired due to the multiple extended redox cycles.…”

The chemical looping conversion of CH 4 has been one of the most promising technologies for achieving the "twocarbon" strategy. Fe 2 O 3 oxygen carrier cannot maintain the excellent release performance of lattice oxygen at high temperature due to the sintering and carbon deposition. Therefore, quaternary La 1−x Sr x Fe 1−y Co y O 3 perovskite was selected as the transfer support of oxygen ions. By using the MOF precursor method, ternary La 0.8 Sr 0.2 FeO 3 was prepared via the introduction of metal Sr into the binary LaFeO 3 . The adsorption energy of CH 4 on the La 0.8 Sr 0.2 FeO 3 was the lowest (−0.054 eV), compared with separate Fe 2 O 3 and LaFeO 3 , and the adsorption energy of free H at the adjacent Fe site was the lowest (1.650 eV). Furthermore, the La 1−x Sr x Fe 1−y Co y O 3 perovskite was successfully synthesized by the doping of Co into the ternary La 0.8 Sr 0.2 FeO 3 . La 0.8 Sr 0.2 Fe 0.8 Co 0.2 O 3 was chosen to composite Fe 2 O 3 oxygen carrier. As m(Fe 2 O 3 ):m(La 0.8 Sr 0.2 Fe 0.8 Co 0.2 O 3 ) = 1:1, the lattice oxygen conversion rate was less than 47% and the selectivity of CO 2 reached 99.5% through the synergistic effect of lattice oxygen and oxygen vacancies. Fe 2 O 3 −La 0.8 Sr 0.2 Fe 0.8 Co 0.2 O 3 increased the lattice oxygen conversion by 17.6%, compared with Fe 2 O 3 −La 0.8 Sr 0.2 FeO 3 . After the CH 4 chemical looping conversion cycles five times, Fe 2 O 3 −La 0.8 Sr 0.2 Fe 0.8 Co 0.2 O 3 still had favorable structural stability and oxidation performance, and the lattice oxygen conversion rate still reached >95%.
