Enhanced reducibility and redox stability of Fe₂O₃in the presence of CeO₂nanoparticles

Abstract

An oxygen-storage material with high reducibility and redox stability was obtained by anchoring isolated CeO2 nanoparticles on Fe2O3 rods after a high-temperature thermal treatment.

Fabrication of CeO2/Fe2O3 composite nanospindles for enhanced visible light driven photocatalysts and supercapacitor electrodes

“…16,21,22 Even though, α-Fe 2 O 3 is considered as one of the most promising pseudocapacitor electrode materials, the high-rate charge/discharge performance and cyclic stability are not fulfilled due to their poor electrical conductivity and metastability. 25 Based on the above consideration, we have attempted to exploit a new impressive visible light reactive hybrid CeO 2 /Fe 2 O 3 nanocomposite photocatalysts with a tailored bandgap for its potential application in photocatalyst and supercapacitors. 25 Based on the above consideration, we have attempted to exploit a new impressive visible light reactive hybrid CeO 2 /Fe 2 O 3 nanocomposite photocatalysts with a tailored bandgap for its potential application in photocatalyst and supercapacitors.…”

Steam catalytic cracking of coal tar over iron‐containing mixed metal oxides

“…There are two reduction peaks of Fe 2 O 3 . The first peak is ascribed to the reduction of Fe 2 O 3 into magnetite Fe 3 O 4 , and the second peak around 720 °C with a higher H 2 uptake is associated with the subsequent multiple reduction of magnetite Fe 3 O 4 to Fe through FeO as an intermediate . With the addition of the second metal oxide, the reduction peaks of the mixed metal oxides show different behaviours.…”

Chemical looping hydrogen production with modified iron ore as oxygen carriers using biomass pyrolysis gas as fuel

“…Many researchers also reported that Fe 2 O 3 , together with CeO 2 , forms a perovskite-type CeFeO 3 , which improved the reversibility of the Fe 2 O 3 redox reaction. 40,[45][46][47] Gu et al 40 reported that the abundant Ce 3+ ions in CeFeO 3 might act as a catalyst to enhance the reducibility of the Ce and Fe oxides. Zhu et al 47 found that the formation of CeFeO 3 enhanced the oxygen mobility of the CeO 2 -Fe 2 O 3 OC.…”
