Preparation of TiO2–MoO3 composite nanofibers by water-based electrospinning process and their application in photocatalysis

Coupling TiO2 nanofibers with other semiconductor metal oxides can effectively extend the light absorbability of to visible range electromagnetic spectrum. This study demonstrates synthesis TiO2–MoO3 composite via electrospinning using Ti and Mo water-soluble precursors. Aqueous solutions these precursors were added a PVP solution in N–N dimethylformamide. The mixture was electrospun, followed by annealing air at 600 °C obtaining oxide nanofibers. fibers characterized thermogravimetry differential thermal analysis, X-ray photoelectron spectroscopy, scanning electron microscopy energy-dispersive transmission microscopy, Fourier-transform infrared diffraction, Raman spectroscopy. diameter between 90 110 nm after annealing, Furthermore, methylene blue dye used investigate photocatalytic activity light. showed best photocalaytic rate constant 0.0018 min−1 while pure MoO3 had 0.0009 0.0008 respectively.
