Preparation of 3-D scaffolds in the SiO2–P2O5 system with tailored hierarchical meso-macroporosity

Herein we report for the first time the synthesis of three-dimensional scaffolds in the binary system SiO2–P2O5 exhibiting different scales of porosity: (i) highly ordered mesopores with diameters of ca. 4nm; (ii) macropores with diameters in the 30–80μm range with interconnections of ca. 2–4 and 8–...
