The removal of certain organic contaminants, including synthetic dyes, from water sources remains a major challenge due to the limited efficiency of conventional water treatment methods. Strategies aimed at converting potentially harmful molecules into less toxic species have been pursued in the last years. In this context, here we synthesized a functional material based on a fiber-based MOF MIL-88A/MoS2, aiming to develop an efficient photocatalyst for mitigating organic contaminants. Photodegradation tests using the MIL-88A/MoS2 powder material indicated efficiency towards methylene blue (MB) dye (employed as a model) greater than 90 % within 120 min. To facilitate the reuse process and prevent the agglomeration of MIL-88A/MoS2 photocatalysts in solution, the MOF/MoS2 was immobilized on PVP/SiO2 fibers produced by solution-blow spinning (SBS). The fibers were subjected to thermal treatment to increase the surface area and lead self-stable fiber-based support for the MOF/MoS2 photocatalyst. The MB removal tests using PVP/SiO2/MOF/MoS2 fibers demonstrated efficiency above 90 % within 48 h. Additionally, it was observed that the PVP/SiO2 fibers also contributed to the adsorption and photodegradation processes of the dye, indicating a synergistic effect. The material’s stability was evaluated over ten reuse cycles, maintaining efficiency. Furthermore, the nanostructured platform demonstrated versatility by effectively treating other dyes, such as methyl orange (MO) and rhodamine B (RhB), as well as the antibiotic tetracycline. These results highlight the material’s potential for remediating organic environmental pollutants, showcasing the fiber’s efficiency and stability MenosThe removal of certain organic contaminants, including synthetic dyes, from water sources remains a major challenge due to the limited efficiency of conventional water treatment methods.
