A method of preparing a porous metal comprises reducing a mixture comprising (I) a source of metal; (II) a solvent such as water; and (III) a structure-directing agent such as octaethylene glycol monododecyl ether to form a liquid crystalline phase in the mixture. The reduction of the mixture having a liquid crystalline phase, for example using zinc metal as reducing agent, provides a porous film having a substantially regular structure and substantially uniform pore size.
L'invention concerne un procédé de préparation d'un métal poreux consistant à réduire un mélange contenant (I) une source de métal; (II) un solvant tel que de l'eau; (III) un agent permettant la formation de la structure, tel que de l'éther d'octaéthylène glycol monododécyle, en vue de former une phase cristalline liquide dans le mélange. La réduction du mélange contenant une phase cristalline liquide, qui utilise, par exemple, du métal zinc comme agent réducteur, entraîne la formation d'un film poreux présentant une structure sensiblement régulière et une dimension des pores sensiblement uniforme.
