Chemical looping hydrogen production (CLHP), a versatile energy conversion and production technology, has garnered extensive attention. CLHP demands redox catalysts with high oxygen capacity, regulatable reactivity, and structural integrity even under harsh operational conditions. Currently, sintering, agglomeration, and inactivation of redox catalysts during cyclic lattice oxygen release and restoration are challenging, hindering the wide industrialization of the chemical looping (CL) process. Moreover, the precise control of activity and reaction rate of the redox catalysts to flexibly accommodate the demands of various reaction substrates remains unclear. This paper introduces the design of a nano-scaled redox catalyst featuring a unique core-shell structure. By precisely controlling the shell thickness, a series of hierarchical Fe₂O₃@SiO₂ redox catalysts were successfully synthesized. Building on this achievement, an in-depth investigation was conducted into the impact of the thickness and spatial structure of the inert support on the stability and mass transfer rate of the redox catalyst, aiming to achieve a perfect balance between these two factors during the CLHP process. A thin shell (70 nm) exhibits excellent cyclic stability, maintaining consistent performance in 30 consecutive redox cycles, while a thicker shell (200 nm) undergoes rapid deactivation due to the formation of a substantial amount of iron silicate. In-situ transmission electron microscopy (TEM) reveals that the SiO₂ shell effectively restricts the agglomeration of Fe₂O₃. The unique core-shell structure and controllable shell thickness offer novel insights into the flexible design of efficient and durable hierarchical redox catalysts with spatial structure.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"106 ","pages":"Pages 1046-1055"},"PeriodicalIF":13.1,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144139153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the historical challenge of high thermal precipitation of V₂O₅ from VO₂⁺ (∼50 °C for 1 day) represents a critical concern. Temperature control can alleviate the problem to a certain extent, however, at the expense of the cost of system design and operation. Herein, we report stable electrolyte chemistry at high temperature. By introducing Cr³⁺ as a stabilizer, it bridges with VO₂⁺ to form a Cr<img>O<img>V^Ⅴ structure, which reduces the electron cloud density of V. Therefore, it combines more tightly with H₂O and prevents its dehydration process. In addition, the dimerization process of VO₂⁺ is also inhibited due to the occupancy of Cr³⁺. As a result, a formed 1.5 M VO₂⁺ electrolyte demonstrates a high stability for over 30 days at 50 °C (v.s. blank for &lt; 1 day at 50 °C). Additionally, the low-temperature precipitation temperature of V²⁺ on the negative side has been reduced from 0 °C of commercial electrolytes to −5 °C. As a proof of concept, a VFB assembled with Nafion 115 membrane demonstrates an energy efficiency (EE) of 80% at 120 mA cm⁻² for 1000 cycles (50 °C). Most importantly, a 4 kW stack can continuously run for ∼1000 cycles with EE of 80% at 120 mA cm⁻² without any heat management.
