Abstract

The in-situ utilization of lunar resources is of great significance to constructing a lunar base. This study investigated the feasibility of using a high titanium lunar soil simulant to develop continuous fiber. The photocatalytic activities of the lunar soil simulant and fiber were compared. The lunar fiber was prepared using the microwave melt-drawing technique, validating the potential of lunar soil to produce continuous fiber. The developed fiber exhibited enhanced photocatalytic performance to degrade organic pollutants in solution. It was found that TiO₂ (Rutile) and Fe nanoparticles were produced in the filament during the spinning of fiber, generating free radicals upon sunlight irradiation. These radicals exhibited photocatalytic properties, thereby enabling the fiber with enhanced photocatalytic performance. The findings of this work not only provide a material solution for the construction of a lunar base, but also expand the application of lunar soil.

月壤连续纤维的光催化性能

月球资源就地利用对月球基地建设具有重要意义。本研究探讨了利用高钛月球土壤模拟剂发展连续纤维的可行性。比较了月球土壤模拟剂和纤维的光催化活性。利用微波熔拔技术制备了月球纤维，验证了月球土壤生产连续纤维的潜力。该纤维对溶液中的有机污染物具有较强的光催化降解性能。结果表明，纤维纺丝过程中产生TiO2（金红石）和Fe纳米颗粒，在阳光照射下产生自由基。这些自由基表现出光催化性能，从而使纤维具有增强的光催化性能。本工作的发现不仅为月球基地的建设提供了材料解决方案，而且拓展了月球土壤的应用。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
