Enhanced hydrogen production reversibility in the MnFe₂O₄-Na₂CO₃ thermochemical cycle via synergistic effect of liquid carbonate and CeO₂ nanoparticles

This study investigates the addition of 3 wt% of TiO₂, SiO₂, and CeO₂ nanoparticles as an anti-sintering strategy to enhance the reversibility of sodium manganese ferrite for hydrogen production. After preliminary tests, TiO₂ NPs were discarded due to cross-reactivity leading to pronounced sintering...

After preliminary tests, TiO₂ NPs were discarded due to cross-reactivity leading to pronounced sintering. SiO₂ NPs hindered the sintering due to the in-situ formation of NaFeO2,SiO2 solid solution but ultimately resulted in irreversible H₂ production. In contrast, CeO₂ NPs demonstrated high stability and chemical compatibility, stabilizing H₂ production at approximately 50 μmol/g, while the reference mixture monotonically lost reversibility in 5 cycles. Notably, combining CeO₂ NPs with a eutectoid (Na0.93Li0.07)2CO3 mixture enhanced H₂ production to 0.18/0.19 mmol/g. As a result, the H2 produced during the 5th cycle was nearly twenty times that of the reference mixture. This improvement was attributed to a synergistic effect between the formation of liquid carbonate and the anti-sintering and oxygen gateway effect of the CeO2 NPs.This project has received funding from the European Union NextGenerationEU (H2PLAN-KC-2021/00002) and the Department of Economic Development, Sustainability and Environment of the Basque Government H2BASQUE-KK-2021/00054.Elsevier202520252025info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10810/72211reponame:Addi.
