摘要

本研究通过三种受控化学方法（溶胶-凝胶法、机械化学法和共沉淀法）合成znfe2o4基陶瓷材料，并在1000-1100℃下进行火花等离子烧结（SPS）固化，用于储能应用。综合表征表明，共沉淀衍生材料具有最小的晶粒尺寸（56 nm）和最高的比表面积（54 m2/g），具有均匀的介孔结构。溶胶-凝胶法是获得陶瓷的最佳方法，在1100℃固结的样品由于其良好的相组成和表面缺陷结构，表现出最佳的电化学性能，电容达到0.02-0.03 F/g。这些材料还表现出额外的磁性功能（剩余磁化强度高达3.94 emu/g），表明集成储能设备的潜力。这些发现有助于开发用于下一代储能应用的环保陶瓷材料，为传统电容器材料提供无铅替代品。

ZnFe2O4 controlled synthesis: key to improving properties of functional ceramic materials for energy storage applications

This study investigates ZnFe₂O₄-based ceramic materials synthesized via three controlled chemical methods (sol-gel, mechanochemical, and coprecipitation) and consolidated by spark plasma sintering (SPS) at 1000–1100 °C for energy storage applications. Comprehensive characterization revealed that coprecipitation-derived materials exhibit the smallest crystallite size (56 nm) and highest specific surface area (54 m²/g) with uniform mesoporous structure. Sol-gel synthesis method proved to be optimal for obtaining ceramics, as samples consolidated at 1100 °C exhibited the best electrochemical performance with capacitance reaching 0.02–0.03 F/g due to their favorable phase composition and surface defect structure. The materials also exhibited additional magnetic functionality (remanent magnetization up to 3.94 emu/g), suggesting potential for integrated energy storage devices. These findings contribute to the development of environmentally friendly ceramic materials for next-generation energy storage applications, offering a lead-free alternative to conventional capacitor materials.

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
