摘要
本文研究了一种简单的制备磁性空心纳米管的方法,这种空心纳米管比表面积大,比表面积为539.36m~2g~(-1)。进一步的研究表明,这种硅酸镁纳米管对于亚甲基蓝具有良好的吸附效果。同时该纳米管具有超磁性,可以很容易的进行磁性分离。该制备方法可以为其他的磁性硅酸盐提供基础和借鉴。
This study reports the fabrication of magnetic hierarchical magnesium silicate hollow nanotubes. The as-prepared magnetic hierarchical hollow nanotubes retained the tubular structure of the templates, which resulted in large surface areas as high as 539.36m~2 g~(-1). Further investigation shows that they are indeed perfect candidates as absorbents for methylene blue(MB). Particularly, this strategy can be extended as a general method to prepare other magnetic metal silicate hollow nanotubes.
