Abstract
Official abstract text for this publication.
Disclosed here is a method for making a nanoporous material, comprising aerosolizing a solution comprising at least one metal salt and at least one solvent to obtain an aerosol, freezing the aerosol to obtain a frozen aerosol, and drying the frozen aerosol to obtain a nanoporous metal compound material. Further, the nanoporous metal compound material can be reduced to obtain a nanoporous metal material.
First claim
Opening claim text (preview).
What is claimed is: 1 . A composition comprising a nanoporous metal material that comprises nanoporous particles or foams having an average or mean diameter of about 100 microns or less, wherein the nanoporous metal material comprises at least about 40 wt. % of elemental metal. 2 . The composition of claim 1 , wherein nanoporous particles or foams comprise a network of interconnected ligaments and struts having an average or mean diameter of about 1000 nm or less. 3 . The composition of claim 1 , wherein the nanoporous metal material comprises at least about 80 wt. % of elemental metal. 4 . The composition of claim 1 , wherein the nanoporous metal material has a porosity of at least about 30%. 5 . The composition of claim 1 , wherein the nanoporous metal material has a porosity of at least about 50%. 6 . The composition of claim 1 , wherein the nanoporous metal material has a density of about 1000 mg/cc or less. 7 . The composition of claim 1 , wherein the nanoporous metal material has a density of about 100 mg/cc or less. 8 . The composition of claim 1 , wherein the elemental metal is silver. 9 . The composition of claim 1 , wherein the elemental metal is copper. 10 . The composition of claim 1 , wherein the nanoporous metal material comprises at least two elemental metals. 11 . The composition of claim 3 , wherein the elemental metal is silver. 12 . The composition of claim 3 , wherein the elemental metal is copper. 13 . The composition of claim 3 , wherein the nanoporous metal material comprises at least two elemental metals.
