Abstract
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.
Claims8
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.
Dependencies are inferred from the claim text.
