Abstract
The invention discloses methods of producing thermally stable mesoporous transition metal oxide compositions by aqueous co-assembly of glycometallates and metal complexes with a surfactant template, without the necessity of the use of stabilizers. Mesoporous (nickel/platinum)-yttria-zirconia materials are also disclosed for use as electrode materials in solid oxide fuel cells. These materials display the highest surface area of any form of (metal)-yttria-stabilized-zirconia, thereby providing significant improvement in the efficiency of solid oxide fuel cells.
