Hierarchically porous CaCO3 monoliths prepared from leaf template

Herein, we demonstrate a simple and cost-effective method to prepare the hierarchically porous CaCO3 monoliths in a large scale by mineralizing gingko leaf templates with a calcium acetate precursor. The resulting products are characterized by FESEM, XRD, TEM and N-2 adsorption. The wide distribution of pore sizes from meso- to macro- and the hierarchical 3D structure endow the resulting products with a variety of application potentials ranging from industry to biomedicine to nanotechnology.
