Method of producing a porous crystalline material with a highly uniform structure

Abstract

Described herein is a scalable, economic, energy and time efficient method for the synthesis of a crystalline uniform nanoporous oxide material by utilizing colloidal particles in solution combustion synthesis. By removing colloids from nanocomposite via chemical etching crystalline uniform porous oxide is prepared with tailored porosity. The produced oxides have high specific surface area, high pore volume, uniform pore structure and high crystallinity. Properties of the oxide can be tuned by the concentration and size of colloids added, which affects the porous structure (mesopore diameter, pore wall thickness, surface area, and pore volume). In principle, this method can be applied to synthesize different high porosity crystalline metal oxides and nanocomposites.
