采用静电纺丝技术和水热法制备了具有分层结构的硅酸镁双壁中空纳米纤维（MSHNFs）。制备的mshfs由许多厚度约为10 nm的超薄纳米片组成，具有高比表面积和大孔体积，在有机分子和重金属离子溶液的净化测试中表现出高的吸附能力和优异的稳定性。此外，由于其独特的结构，可以很容易地通过重力沉降从溶液中分离出来。
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 areaand large pore volume 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.
