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.
