Abstract:

In order to prepare light photocatalysts with large specific surface area, aiming at the problem that most of polymer carriers in electrospinning are polluted and non-renewable, ZnAc/silk fibroin(SF) nanofiber films were prepared by coaxial electrospinning using silk fibroin as carrier, and then ZnAc/SF nanofiber films were immersed in Na2S solution to prepare ZnS/SF nanofiber films. Finally, porous ZnO films were obtained by calcination. The structure, element composition, surface morphology and optical properties of the samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, Scanning electron microscope and UV-Vis absorption spectra. Besides, the photocatalytic performance of samples were studied by MB degrading tests. The results show that the porous ZnO film is a mesoporous network composed of 10-20 nm nanoparticles with the capability of absorbing ultraviolet light. The film is stronger in photocatalytic activity than the ZnS/C nanofiber film, and has the degradation efficiency of methylene blue up to 99.5%. In addition, porous ZnO films can be easily recycled and reused, and the degradation efficiency reaches 91% after four cycles.

Key words: dyeing waste water, porous ZnO film, coaxial electrospinning, photocatalytic property, recycling
