Electrospinning Preparation and Visible-Light Photocatalytic Activity of Single Crystal MoO(3) Nanoplatelets

PVP/(NH(4))(6)Mo(7)O(24)center dot 4H(2)O nanofibers was fabricated by electrospinning technique and then the electrospun precursors were calcined at different temperatures. In order to study the growth process of the crystal, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) were used to characterize the samples. Importantly, the visible-light photocatalytic activity of samples was evaluated by employing methylene blue (MB) as a probe. The results suggest that MoO(3) nanoplatelets are obtained at 500 degrees C and the best photocatalytic activity is achieved when using MoO(3) nanoplatelets as a catalyst.
