LaNixFe1−xO3 as flexible oxygen or carbon carriers for tunable syngas production and CO2 utilization

Mixed oxides as multi-functional reaction media for chemical looping catalysis

“…An extensively investigated topics is methane to syngas/H 2 conversion. 95,[109][110][111][112][113][114][115][116][117]123,[125][126][127]130,136,185,[193][194][195][196][197][198][199][200][201][202][203][204][205][206][207][208] A few other studies explored a phase transition sorbent concept where a single mixed oxide particle combines the function of a redox oxide (for oxygen separation), a carbonate sorbent (for CO 2 separation), and a catalyst (to catalyze chemical reactions). 95,123,130,197,198,[209][210][211] For instance, a recent study adopted the chemical looping strategy to selectively oxidize ammonia with excellent NO selectivity for nitric acid production.…”

Recent Advances in Coke Management for Dry Reforming of Methane over Ni-Based Catalysts

“…Moreover, the Ni/Fe ratio affects the syngas ratio [221]. Yao et al demonstrated that the PrBaMn 1.6 Ni 0.3 Fe 0.1 O 5+δ with uniform-sized Ni-Fe alloy exhibits negligible coking during a 40 h reaction under more severe coking conditions (14 bar) [222].…”

Tailoring Catalytic and Oxygen Release Capability in LaFe1–xNixO3 to Intensify Chemical Looping Reactions at Medium Temperatures

“…Applying such Fe–Ni-based perovskite oxygen carriers in chemical looping and even heterogeneous catalysis is not rare. Studies have confirmed that high methane conversion can be achieved at relatively low temperatures on these perovskite oxygen carriers. , However, it is still challenging for Ni-containing perovskite oxygen carriers to avoid severe carbon deposition in the reduction process because of the strong catalytic effect of Ni on methane cracking. Fortunately, the Ni-doping-induced lattice distortion and Fe–Ni interactions weaken the lattice oxygen bonding strength of the perovskite oxygen carriers, significantly intensifying the oxygen release to remove carbon.…”
