ABSTRACT:
The invention is a method for producing a metal oxide product by steps including absorbing a liquid solution of metal oxide precursors onto crystalline or microcrystalline, porous structured organic material capable of being combusted at elevated temperatures; heating the organic material containing the absorbed solution for a time and at a temperature sufficient to vaporize the liquid, convert the metal oxide precursors to metal oxides, and combust the organic material. The metal oxide products have been found to retain a high specific surface area (porous structure) even when subjected to elevated temperatures, which makes them ideally suited for use as catalyst materials.
