具有多级结构的硅酸镁双层空心纳米纤维的制备以及在水污染物处理方面的应用研究

Novel magnesium silicate double-walled hollow nanofibers (MSHNFs) with a hierarchical nanostructure have been successfully fabricated by combining the electrospinning technique with the hydrothermal method. The as-prepared MSHNFs are composed of numerous ultrathin nanosheets with a thickness of about 10 nm and have a high specific surface area and large pore volume. The MSHNFs exhibit high adsorption capacity and excellent stability in the purification test with organic molecules. Moreover, the MSHNFs could be easily recycled by gravitational sedimentation due to their unique one-dimensional nanostructural property.
