A novel yet straightforward one-pot synthesis technique was developed to grow silica nanorods on the interior and exterior surfaces of a porous, inorganic scaffold. Growth of the rods on the surface, versus in the bulk, was achieved by functionalizin

Kaolinite–silica nanocomposites with a green porosity ranging from 75% to 87% were prepared using a freeze-casting technique. The initial solids loading values (kaolinite platelets plus silica nanospheres) greatly influence the sintering behavior a
