Integrated adsorption and photocatalytic removal of methylene blue dye from aqueous solution by hierarchical Nb2O5@PAN/PVDF/ANO composite nanofibers
This work presents the development of hierarchical niobium pentoxide (Nb2O5)-based composite nanofiber membranes for integrated adsorption and photocatalytic degradation of methylene blue (MB) pollutants from aqueous solutions. The Nb2O5 nanorods were vertically grown using a hydrothermal process on a base electrospun nanofibrous membrane made of polyacrylonitrile/polyvinylidene fluoride/ammonium niobate (V) oxalate hydrate (Nb2O5@PAN/PVDF/ANO). They were characterized using field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) analysis, and Fourier transform infrared (FTIR) spectroscopy. These composite nanofibers possessed a narrow optical bandgap energy of 3.31 eV and demonstrated an MB degradation efficiency of 96 % after 480 min contact time. The pseudo-first-order kinetic study was also conducted, in which Nb2O5@PAN/PVDF/ANO nanofibers have kinetic constant values of 1.29 × 10−2 min−1 and 0.30 × 10−2 min−1 for adsorption and photocatalytic degradation of MB aqueous solutions, respectively. These values are 17.7 and 7.8 times greater than those of PAN/PVDF/ANO nanofibers without Nb2O5 nanostructures. Besides their outstanding photocatalytic performance, the developed membrane materials exhibit advantageous characteristics in recycling, which subsequently widen their practical use in environmental remediation applications.
期刊介绍：
Nano Materials Science (NMS) is an international and interdisciplinary, open access, scholarly journal. NMS publishes peer-reviewed original articles and reviews on nanoscale material science and nanometer devices, with topics encompassing preparation and processing; high-throughput characterization; material performance evaluation and application of material characteristics such as the microstructure and properties of one-dimensional, two-dimensional, and three-dimensional nanostructured and nanofunctional materials; design, preparation, and processing techniques; and performance evaluation technology and nanometer device applications.
