Liquid crystal phase templated mesoporous platinum alloy
Liquid crystal phase templated mesoporous platinum alloy
The reduction of metal salts dissolved in the aqueous domains of the lyotropic liquid crystalline phases of surfactants provides a versatile route to a range of mesoporous metals with aligned pore systems having a high degree of spatial periodicity. Here we report that the co-reduction of binary mixtures of metal compounds dissolved in the hexagonal phase of a non-ionic surfactant leads to bimetallic alloy powders that have a long-ranged porous nanostructure and high specific surface areas. These results indicate that the use of liquid crystalline reaction mixtures could provide a new route to alloys of importance for applications in catalysis.

Abstract
The reduction of metal salts dissolved in the aqueous domains of the lyotropic liquid crystalline phases of surfactants provides a versatile route to a range of mesoporous metals with aligned pore systems having a high degree of spatial periodicity. Here we report that the co-reduction of binary mixtures of metal compounds dissolved in the hexagonal phase of a non-ionic surfactant leads to bimetallic alloy powders that have a long-ranged porous nanostructure and high specific surface areas. These results indicate that the use of liquid crystalline reaction mixtures could provide a new route to alloys of importance for applications in catalysis.
