Herein, Fe based metal-organic framework (Materials Institute Lavoisier: MIL100) and its nanocomposites with different titania nanofiber (TNF) amounts (0.05, 0.07 and 0.09 g denoted as MIL100/TNF5, MIL100/TNF7 and MIL100/TNF9) were synthesized using a facile and green procedure at room temperature and atmospheric pressure. The TNF inorganic nanofiber was synthesized using the electrospinning method. The nanomaterials were fully characterized. They were used for visible-light photocatalytic degradation of Methylene Blue (MB). The surface area of MIL100/TNF7 was 1194.48 m2/g. The data indicated the MIL100 diameters ranging from 22 to 72 nm. The decolorization percentage of the synthesized materials at different dosages including 0.003, 0.004, 0.005, and 0.006 g was 39.80, 54.96, 63.31, and 72.10% for MIL100, 25.50, 26.81, 29.23, and 35.62% for TNF and 46.42, 70.85, 88.3, 97.96 and 99.40% for MIL100/TNF7, respectively. The MIL100/TNF7 nanomaterial had higher dye degradation ability, reusability, and stability over five cycles. Dye degradation followed first-order kinetics.
