摘要

本研究以钢渣为基体，通过碳封存技术将其转化为固碳材料，并与硝酸钠相变材料复合，采用冷压烧结法制备了一种新型固碳储热一体化复合材料。通过正交试验优化碳封存条件，确定最佳反应条件为：温度75℃、CO

压力0.85 MPa、液固比35、搅拌速率950 r/min。在此条件下，温度提升至95℃并反应4 h后，固碳量达到294 kgCO

钢渣

。扫描电子显微镜(SEM）观察显示，硝酸钠均匀贴合于固碳钢渣孔隙之中；X射线衍射(XRD）分析表明二者具有良好的化学相容性，仅为物理混合。热物性测试结果表明，固碳钢渣/硝酸钠复合材料的最佳负载量为50%，其熔点为303.2℃，相变潜热值为81.9 J/g，导热系数为0.866 W/(m·K)。经过300次加热/冷却循环后，该复合材料展现出良好的循环稳定性。与钢渣硝酸钠复合相变储热材料相比，其储热性能更为优异。本研究不仅为固废资源的高效利用提供了新的途径，还为开发高性能复合相变储热材料提供了实验依据，推动了固碳与储热一体化技术的发展，为清洁低碳能源转型中的可再生能源储存技术提供了重要的技术支持。

Abstract

This study investigates the conversion of steel slag into a carbon-sequestering matrix through accelerated mineral carbonation. The resulting CO

-fixing steel slag is combined with sodium nitrate phase-change material (PCM) using cold-press sintering

producing a dual-functional composite capable of simultaneous carbon sequestration and thermal energy storage. An orthogonal experimental design is employed to optimize carbonation parameters

with optimal conditions identified as 75℃

0.85 MPa CO

pressure

a liquid-to-solid ratio of 35

and a stirring speed of 950 r·min

-1

. Further carbonation conducted at 95℃ for 4 h under optimized conditions yields a carbon sequestration capacity of 294 kg CO

/t steel slag. Scanning electron microscopy analysis reveals homogeneous impregnation of sodium nitrate within the pore structure of the CO

-fixing steel slag. X-ray diffraction analysis demonstrates high chemical compatibility between the constituents

confirming the absence of chemical reactions and indicating purely physical interactions. Thermal characterization shows that the composite containing 50% CO

-fixing steel slag exhibits a melting temperature of 303.2℃

a latent heat capacity of 81.9 J/g

and a thermal conductivity of 0.866 W/(m·K). The composite also maintains stable thermal performance over 300 heating-cooling cycles. Compared with previously reported steel slag-sodium nitrate PCM composites

this system exhibits markedly enhanced thermal energy storage performance. Overall

this study proposes a sustainable dual-functional strategy for the high-value utilization of steel slag while providing systematic experimental validation for the development of high-performance composite PCMs. Furthermore

it demonstrates the technical feasibility of coupling carbon capture with thermal energy storage

offering a robust materials-level foundation for renewable energy storage technologies in the t

ransition toward clean

low-carbon energy systems.
