Abstract
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.
Claims10
A method of preparing a porous metal-based material having a substantially regular structure and uniform pore size which comprises reducing a mixture comprising:
- a source of metal;
- a solvent;
- and a structure-directing agent present in an amount sufficient to form a liquid crystalline phase in the mixture, to form a composite of metal-based material and organic -matter, and optionally removing organic matter from the composite.
A porous metal-based material having a substantially regular structure and substantially uniform pore size, wherein the pore size is in the mesoporous range.
