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 salt material that comprises nanoporous particles or foams having a mean diameter of about 100 microns or less, wherein the nanoporous metal salt material comprises an elemental metal and a salt, the elemental metal is silver, the nanoporous metal salt material has a porosity of at least about 30 percent, and the nanoporous metal salt material has a density of about 1000 mg/cc or less. 2. The composition of claim 1 , wherein the nanoporous particles or foams comprise a network of interconnected ligaments and struts having a mean diameter of about 1000 nm or less. 3. The composition of claim 1 , wherein the nanoporous metal salt material has a porosity of at least about 50%. 4. The composition of claim 1 , wherein the nanoporous metal salt material has a density of about 100 mg/cc or less. 5. The composition of claim 1 , wherein the nanoporous metal salt material has a porosity of at least about 80 percent. 6. The composition of claim 1 , wherein a mean diameter of the nanoporous particles or foams is about 200 nm or less. 7. The composition of claim 1 , wherein at least about 30 percent of the nanoporous particles or foams have diameters that are within about 70 percent to 130 percent of the mean diameter. 8. The composition of claim 1 , wherein at least about 30 percent of the nanoporous particles or foams have diameters that are within about 1-5 microns, 5-10 microns, 10-20 microns, 20-30 microns, or 30-50 microns.
