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 m2 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.
