Magnesium silicate double‐walled hollow nanofibers (MSHNFs) with a hierarchical nanostructure have been successfully fabricated by combining the electrospinning technique with a hydrothermal method. The as‐prepared MSHNFs are composed of numerous ultrathin nanosheets with a thickness of approximately 10 nm and have a high specific surface area (632.2 m 2 g −1 ) and large pore volume (0.92 cm 3 g −1 ). The MSHNFs exhibit high adsorption capacity and excellent stability in a purification test with organic molecules and a solution of heavy‐metal ions. Moreover, the MSHNFs can be easily separated from solution by gravitational sedimentation owing to their unique structure.
