摘要: A general one-step route has been developed for the selective synthesis of magnesium silicate hollow spheres, core−shell and nanotubes. The formation mechanism was studied. concentration NaOH played an important role in while addition glycol a critical These nanostructures usually have BET surface areas 200−400 m2/g. Further investigation their ion exchange performance shows that they are indeed perfect candidates as absorbents heavy metal ions including Pb2+, Cr3+, Cd2+, etc.
