A magnesium carbonate recyclable template to synthesize micro hollow structures at a large scale

摘要

A facile strategy by using magnesium carbonate as the recyclable template has been developed to synthesize a variety of uniform inorganic hollow structures whose composition, size and shape can be readily modulated to generate interesting structures such as TiO_2, A1_2O_3, SiO_2, Gd_2O_3 and MO microtubes and TiO_2, SiO_2 hollow microboxes.
