A simple and efficient route to prepare supported nanocrystalline oxides is presented. The synthesis procedure, i.e. in situ autocombustion of a glycine complex, allows the production nanocrystals porous matrix presenting larger pore size. An example successful formation 2-5 nm given for single oxide (Fe(2)O(3)), mixed-oxide structure (LaCoO(3) perovskite-type) nickel-doped oxide.
