Facile synthesis of magnetic magnesium silicate hollow nanotubes with high capacity for removal of methylene blue

This study reports the fabrication of hierarchical magnetic magnesium silicate hollow nanotubes . Owing to its unique structure and high surface area (539.36 m 2  g −1 ), the as-prepared hierarchical magnetic hollow nanotubes exhibit excellent adsorption performance on uptake of methylene blue (MB). Particularly, this strategy can be extended as a general method to prepare other magnetic metal silicate hollow nanotubes.
